Axolotl Tank Setup Guide: Step-by-Step Equipment, Layout, and Safe Defaults for New Keepers

Setting up an axolotl tank correctly before the animal arrives is the single most consequential decision in axolotl keeping. A cycled, temperature-stable, properly equipped tank prevents the vast majority of health emergencies that send new keepers to veterinary forums in the first three months. This guide walks through every step of the process, from choosing the right tank and equipment through cycling, temperature planning, and the first-week acclimation routine, with safe defaults at each decision point. If you follow this sequence and do not skip the cycling step, you will have a tank that supports a healthy axolotl for a decade or more.

What equipment do you need before you start?

A complete axolotl tank setup requires specific equipment chosen for the species’ biology. Axolotls are cold-water, bottom-dwelling amphibians with sensitive gills, no tolerance for ammonia, and a feeding method that creates impaction risk with the wrong substrate. Every item on this list addresses one of those constraints.

The non-negotiable shopping list

Before purchasing an axolotl, you need all of the following assembled, tested, and running:

  • Tank: 20-gallon long minimum for one adult axolotl. A 29-gallon or 40-gallon breeder is strongly recommended because the larger water volume buffers temperature and chemistry swings. For each additional axolotl, add at least 10 gallons. Floor space matters more than height; axolotls rarely use the upper water column. A long, wide tank is always better than a tall, narrow one. Full sizing logic is covered in the tank size guide.

  • Filter: A sponge filter driven by an air pump is the simplest and safest starting choice. Sponge filters provide biological and mechanical filtration with minimal water current. Canister filters with adjustable flow and a spray bar are the upgrade option for larger tanks. Hang-on-back filters work if the outflow is baffled to reduce current. Axolotls are stressed by strong flow, and sustained directional current causes gill curl. The filtration guide covers filter comparison in detail.

  • Liquid test kit: API Freshwater Master Test Kit or equivalent. Tests ammonia, nitrite, nitrate, and pH. Test strips exist but are less accurate and less reliable for the narrow tolerances axolotls require. You will use this kit daily during cycling and weekly after the tank is established.

  • Dechlorinator: Seachem Prime or equivalent water conditioner that neutralizes chlorine, chloramine, and temporarily detoxifies low-level ammonia. Every water addition to the tank must be treated. Chlorine and chloramine are directly toxic to amphibian skin and gills (source: Axolotl.org).

  • Thermometer: A digital aquarium thermometer with min/max memory, placed at axolotl level (not near the filter outflow or a window). You need to know the actual temperature the animal experiences, not the room temperature or the water surface temperature.

  • Hides: At least one hide per axolotl. PVC pipe sections, ceramic aquarium caves, or smooth-edged terracotta pots. Axolotls are nocturnal and light-sensitive; hides are a welfare requirement, not a decoration. The hides and enrichment guide covers options and placement.

  • Ammonia source for cycling: Pure ammonia (no surfactants, no fragrances) for fishless cycling. Dr. Tim’s Ammonium Chloride is a commonly used product. You cannot skip cycling, and cycling requires an ammonia source.

Optional but recommended

  • Aquarium chiller or clip-on fan: Required if your room temperature exceeds 72 degrees Fahrenheit at any point during the year. In most climates, summer temperatures push ambient room air above axolotl-safe range. A chiller is the most reliable cooling solution. Clip-on fans provide evaporative cooling that works for moderate heat but fails in sustained heat waves. The chiller guide and hot weather setup cover equipment selection.

  • Live plants: Java fern, anubias, and elodea tolerate cool water and low light. Plants provide additional cover, minor nutrient uptake, and surface area for beneficial bacteria. They are not a substitute for mechanical filtration. Silk plants are an alternative if you want cover without plant maintenance. Avoid plastic plants with sharp edges that can damage gill filaments. The plants guide covers species selection.

  • Lid or mesh cover: Axolotls occasionally lunge at the water surface during feeding. A mesh or glass cover prevents escape and reduces evaporation. Avoid tight-fitting lids that trap heat.

Step 1: Choose the right tank and placement

The tank you choose and where you place it determine whether you can maintain stable temperature and water quality for the life of the animal. Getting this wrong creates problems that no amount of equipment can fix after the fact.

A 20-gallon long (30 inches by 12 inches by 12 inches) is the absolute minimum for a single adult axolotl. The 40-gallon breeder (36 inches by 18 inches by 16 inches) is the most commonly recommended size in experienced keeper communities because the additional floor space and water volume make temperature stability, waste dilution, and territorial comfort substantially easier to maintain. From reviewing common axolotl health presentations in keeper forums, tanks under 20 gallons are disproportionately represented in ammonia spike and heat stress incidents because the smaller water volume amplifies every fluctuation.

Why footprint matters more than volume

Axolotls are benthic animals. They walk along the bottom, rest on the bottom, and feed from the bottom. A 20-gallon tall tank (24 inches by 12 inches by 16 inches) has the same volume as a 20-gallon long but 20 percent less floor space. That difference matters for an animal that almost never swims above the midline. Experienced axolotl keepers we work with consistently recommend optimizing for footprint when choosing between tank shapes of similar volume.

Placement rules

  • Away from direct sunlight. Sunlight raises water temperature unpredictably and promotes algae blooms that degrade water quality and compete with the nitrogen cycle.
  • Away from heat sources. Radiators, space heaters, ovens, and south-facing windows in warm climates. Even intermittent heat exposure from a nearby appliance can push water above the safe range.
  • On a surface rated for the weight. A 20-gallon tank filled with water, substrate, and equipment weighs approximately 225 pounds (102 kilograms). A 40-gallon breeder weighs approximately 450 pounds (204 kilograms). Standard furniture is not rated for this. Use a dedicated aquarium stand or a structurally verified surface.
  • Near a power outlet and water source. You will be doing weekly water changes for years. A tank placed far from a water source turns routine maintenance into an obstacle that leads to skipped changes.
  • In a room where you can control temperature. Basements and ground-floor rooms with air conditioning are ideal. Attic rooms and sunrooms are problematic because they amplify seasonal temperature swings.

Step 2: Substrate selection (safety first, aesthetics second)

Substrate choice is a safety decision with direct veterinary consequences. Axolotls feed by suction, rapidly opening their mouths to create a vacuum that pulls in food along with anything near it. The wrong substrate causes gastrointestinal impaction, one of the most common and most preventable emergencies in captive axolotls (source: Axolotl Central).

Safe substrate options

Bare bottom is the safest option and the easiest to maintain. There is no impaction risk, waste is visible and easy to remove, and cleaning requires nothing more than a turkey baster or gravel vacuum. Bare bottom does not harm axolotls. Some keepers worry about the animal losing traction on smooth glass, but axolotls adapt to bare glass without documented welfare problems. If traction concerns you, a thin layer of aquarium-safe tiles or slate pieces provides grip without impaction risk.

Fine sand with a grain size below 1 millimeter is the other safe option. Fine sand passes through the digestive tract if accidentally ingested during feeding. Sand provides a more natural footing and allows axolotls to engage in substrate-sifting behavior. The trade-off is maintenance: sand requires periodic stirring to prevent anaerobic gas pockets, and waste sits on or just below the surface rather than being immediately visible. Do not use sand for juvenile axolotls under 6 inches (15 centimeters) in length; the impaction risk is higher in smaller animals. The full substrate comparison is in the substrate guide.

What to avoid

Gravel is never safe for axolotls. No gravel size within the standard aquarium gravel range is safe. Pieces large enough to resist suction are still mouthed and occasionally swallowed by adult axolotls during feeding. Gravel impaction is a veterinary emergency that requires surgical intervention or euthanasia in severe cases. This is not a “some keepers use it” gray area. Every major axolotl care resource, rescue organization, and exotic veterinary reference identifies gravel as an impaction hazard (source: Lotl Care).

Crushed coral, colored gravel, and glass beads carry the same impaction risk as standard gravel plus additional chemical concerns from dyes and coatings.

Large river rocks that are individually too big to fit in the axolotl’s mouth (larger than the animal’s head) are acceptable as decorative elements placed on a bare bottom or sand layer, but they do not function as a substrate. Ensure no gaps between rocks where an axolotl limb could become trapped.

Step 3: Install filtration and understand why the nitrogen cycle matters

Filtration is the life-support system for your axolotl. It serves two purposes that cannot be separated: mechanical filtration removes visible debris from the water, and biological filtration converts toxic ammonia into less toxic nitrate through the nitrogen cycle. Without biological filtration, ammonia from the axolotl’s waste, uneaten food, and gill secretions accumulates to lethal levels within days.

How the nitrogen cycle works

The nitrogen cycle is a bacterial process that happens in every healthy aquarium:

  1. Your axolotl produces ammonia through waste, respiration, and gill function. Uneaten food also decomposes into ammonia.
  2. Beneficial bacteria (Nitrosomonas species) colonize the filter media and convert ammonia into nitrite.
  3. A second group of bacteria (Nitrospira species) convert nitrite into nitrate.
  4. Nitrate accumulates in the water at much lower toxicity and is removed through regular partial water changes.

Both ammonia and nitrite are acutely toxic to axolotls at any detectable level. The target for both in a cycled, stable tank is 0 ppm, always. Nitrate should be kept below 20 ppm, with 40 ppm as the absolute ceiling (Axolotl.org).

Choosing a filter type

Sponge filters are the default recommendation for axolotl tanks. They provide excellent biological filtration surface area, produce very gentle water movement, are inexpensive, and are nearly impossible to over-power in a 20 to 40-gallon tank. A sponge filter rated for your tank size, connected to an appropriately sized air pump, is the simplest setup that meets the axolotl’s needs. For a 20-gallon tank, a sponge filter rated for 20 to 40 gallons paired with an adjustable air pump provides adequate turnover without excessive flow.

Canister filters are the upgrade option for keepers who want higher mechanical filtration capacity or who run tanks of 40 gallons or larger. Canister filters must have adjustable flow control, and the return line should use a spray bar positioned along the tank’s back wall to diffuse the outflow across the water surface rather than creating a directional jet. Without a spray bar or baffle, most canister filters produce too much current for axolotl comfort. Detailed filter comparison is covered in the filtration guide linked above.

Hang-on-back filters are a middle option. They work if you baffle the outflow with a pre-filter sponge or a water bottle baffle to break the falling-water current. Unbaffled hang-on-back filters create surface agitation and downward current that axolotls find stressful, particularly when the return flow is aimed toward a resting area.

Flow control is not optional

Axolotls are sensitive to sustained water current. Their feathery external gills act as drag surfaces, and chronic exposure to directional flow causes gill curl, a condition where the gill filaments fold forward from sustained water pressure. Gill curl is reversible if caught early and the flow is corrected, but persistent cases can lead to permanent gill deformation. The current and flow control guide covers baffle methods and flow-rate guidelines.

Position the filter outflow so that no resting area receives direct current. Hides should be placed in low-flow zones. If you see your axolotl’s gills consistently angled forward toward its head, check the flow rate and direction before investigating other causes.

Step 4: Cycle the tank before any axolotl enters the water

The nitrogen cycle must be established before you add your axolotl. This is not a suggestion. Placing an axolotl into an uncycled tank exposes it to ammonia and nitrite spikes that cause gill damage, chemical burns, immune suppression, and organ stress that can kill within days to weeks. From reviewing axolotl veterinary presentations and rescue intake data, the single most common cause of illness in newly acquired axolotls is an uncycled or incompletely cycled tank (source: Axolotl Central).

Fishless cycling step by step

  1. Set up the tank fully with substrate (if using sand), filter running, heater removed (axolotls do not need a heater), dechlorinated water, and all equipment positioned as it will remain during operation.
  2. Add ammonia to the tank water to reach a concentration of 2 to 4 ppm. Use pure ammonia (Dr. Tim’s Ammonium Chloride or equivalent). Add it slowly and test with your liquid kit.
  3. Test daily. Measure ammonia, nitrite, and nitrate every day using your liquid test kit. Record the results in a log.
  4. Wait for ammonia to drop. After several days to two weeks, Nitrosomonas bacteria will colonize the filter media and begin converting ammonia to nitrite. You will see ammonia decline and nitrite rise. This is expected.
  5. Wait for nitrite to drop. Nitrospira bacteria colonize more slowly. When nitrite begins to decline, the second stage of the cycle is establishing. Nitrate will begin to appear.
  6. Re-dose ammonia as needed. When ammonia drops to 0 ppm, re-dose to 2 ppm to keep feeding the bacterial colony. You need enough bacteria to handle the ongoing waste load of a live axolotl, not just a one-time pulse.
  7. Confirm the cycle is complete. The tank is cycled when it can process 2 ppm of ammonia to 0 ppm ammonia and 0 ppm nitrite within 24 hours, consistently. This typically takes 4 to 8 weeks. Some tanks cycle faster with seeded filter media from an established aquarium; others take longer in cool water because bacterial growth rates slow below 20 degrees Celsius (68 degrees Fahrenheit).
  8. Do a large water change (50 to 80 percent) to reduce accumulated nitrate before adding the axolotl. Match the replacement water to the tank’s temperature and treat with dechlorinator.

The tank cycling guide covers the fishless-cycle process in full detail, including troubleshooting stalls and seeded-media shortcuts.

How to confirm the tank is cycled

Run the confirmation test: dose ammonia to 2 ppm, then test again 24 hours later. If ammonia reads 0 ppm, nitrite reads 0 ppm, and nitrate has increased, the cycle is complete. Run this confirmation test at least twice on consecutive days. A single pass is not reliable; bacterial populations fluctuate during establishment.

Do not rely on water clarity as a proxy for cycling. Water can appear perfectly clear while ammonia and nitrite are at toxic levels. The test kit is the only reliable indicator.

Step 5: Set up a temperature control plan

Axolotls are cold-water amphibians. The safe water temperature range is 60 to 68 degrees Fahrenheit (16 to 20 degrees Celsius), with the optimal range at 60 to 64 degrees Fahrenheit (16 to 18 degrees Celsius). Sustained temperatures above 72 degrees Fahrenheit (22 degrees Celsius) are dangerous. Above 75 degrees Fahrenheit (24 degrees Celsius), axolotls experience immune suppression, increased susceptibility to fungal and bacterial infection, and organ damage that can be fatal within days (Axolotl.org).

Axolotls do not need a heater. A ceramic heat emitter (CHE) or aquarium heater is not appropriate for this species. The challenge with axolotls is keeping water cool enough, not warm enough. If your room temperature stays between 60 and 68 degrees Fahrenheit year-round, no temperature-control equipment is needed. Most keepers in temperate and warm climates need a cooling plan for at least part of the year.

Cooling options by climate situation

Mild climates (room temperature occasionally reaches 72 to 75 degrees Fahrenheit in summer): A clip-on aquarium fan positioned to blow across the water surface provides evaporative cooling that can reduce water temperature by 2 to 4 degrees Fahrenheit. This approach works in dry heat but is less effective in humid conditions where evaporation slows. Monitor daily with your min/max thermometer.

Warm climates (room temperature regularly exceeds 75 degrees Fahrenheit): An aquarium chiller is the reliable solution. Chillers are the most expensive single piece of axolotl equipment, typically ranging from $150 to $400 depending on capacity. However, a chiller is a one-time purchase that eliminates the daily anxiety of summer temperature monitoring. Size the chiller to your tank volume and follow the manufacturer’s specifications for flow rate. The chiller guide linked in the equipment section above covers sizing and installation.

Emergency cooling (unexpected heat spike above 75 degrees Fahrenheit): Frozen water bottles (filled with dechlorinated water, sealed, and frozen) can be floated in the tank as a temporary emergency measure. This drops temperature locally but creates uneven cooling and must be refreshed every few hours. It is a stopgap, not a plan. The hot weather setup guide linked in the equipment section covers emergency protocols.

Air conditioning in the room is an effective passive solution if you can maintain the room at 68 degrees Fahrenheit or below. Many experienced keepers in warm climates keep their axolotl tank in a basement or air-conditioned room and consider the air conditioning cost part of the animal’s care budget.

Step 6: Arrange hides, plants, and decor

With the tank cycled and temperature-stable, arrange the interior. Axolotls are nocturnal, light-sensitive animals that spend daylight hours resting in sheltered areas and become active at dusk and after dark. Tank layout should prioritize cover, low light, and clear sightlines between the axolotl and its food.

Hides

Place at least one hide per axolotl. Hides should be:
– Large enough for the axolotl to fit entirely inside without squeezing
– Smooth-edged (no rough ceramic, sharp rock edges, or jagged plastic)
– Opaque (the point is light exclusion and visual security)
– Positioned in a low-flow zone away from filter outflow

PVC pipe (3-inch or 4-inch diameter, cut to 6 to 8 inches long) is the simplest, cheapest, most cleanable hide option. Ceramic aquarium caves, terracotta pots (check for drainage holes that could trap a limb), and commercially made resin hides are all acceptable. Avoid painted or coated decorations that could leach chemicals into cool, slightly acidic water over time.

Plants

Live low-light plants that tolerate cool water (60 to 68 degrees Fahrenheit) add cover, surface area for beneficial bacteria, and minor nitrate uptake. Suitable species include:

  • Java fern (Microsorum pteropus): Attach to driftwood or rocks with fishing line or glue; do not bury the rhizome in substrate. Extremely tolerant of neglect and low-light conditions.
  • Anubias (Anubias barteri): Same attachment method as java fern. Slow-growing, tolerant of low light and cool water.
  • Elodea (Egeria densa): Can be planted in sand or left floating. Grows rapidly and absorbs nitrate, but may need periodic trimming.
  • Java moss (Taxiphyllum barbieri): Attach to decor. Provides dense cover at the substrate level.

Silk plants are an alternative if you prefer zero plant maintenance. Choose silk over plastic; hard plastic leaves can abrade gill filaments. The plants guide linked in the equipment section covers species selection and placement in detail.

Lighting

Axolotls have no eyelids and are photosensitive. Bright overhead lighting causes behavioral stress (glass surfing, hiding refusal, reduced feeding). A low-wattage LED on a timer providing approximately 12 hours of subdued light and 12 hours of darkness is sufficient for plant growth and a consistent day-night cycle. Direct sunlight on the tank is not acceptable: it raises water temperature and drives algae overgrowth. The lighting guide covers fixture options.

Step 7: Add the axolotl (acclimation and first-week monitoring)

The tank is cycled, temperature-stable, equipped, and arranged. Now you can add the animal.

Acclimation procedure

Transport the axolotl in a sealed bag or container with water from its previous environment (breeder, pet store, or shipping container). Float the sealed bag in your tank for 15 to 20 minutes to equalize temperature. Then, over the next 20 to 30 minutes, gradually add small amounts of your tank water to the bag every 5 minutes to acclimate the animal to your water chemistry. When the bag water is roughly 50 percent your tank water, gently release the axolotl into the tank. Do not dump the bag water into your tank; it may contain elevated ammonia from transport.

First-week checklist

The first week after adding your axolotl is a critical monitoring period. The animal is adjusting to new water chemistry, new surroundings, and the stress of transport.

  • Test water parameters daily for the first two weeks. Ammonia and nitrite should remain at 0 ppm. The bioload from a live axolotl is different from the ammonia doses used during cycling; monitor for any spike.
  • Check temperature twice daily (morning and evening). Transport stress plus a new thermal environment can coincide with seasonal temperature shifts.
  • Offer food after 24 to 48 hours. Many axolotls refuse food for the first day or two in a new tank. This is normal stress behavior. Offer a small earthworm segment or a few pellets; remove uneaten food after a few hours.
  • Observe gill condition. Healthy gills are feathery, erect, and fan outward. Forward-curled gills within the first week may indicate flow stress; check filter positioning. Pale or shrunken gills may indicate water quality problems; test immediately.
  • Minimize handling and tank activity. No unnecessary tank rearrangement, no bright overhead lights left on, no tapping on the glass. Let the animal settle.
  • Do not add a second axolotl during this period. Establish the first animal’s baseline before introducing any cohabitant.

Ongoing maintenance: keeping the system stable

A properly set up and cycled axolotl tank requires consistent, predictable maintenance. The goal is parameter stability, not perfection in any single measurement. Stable, consistent conditions prevent more health problems than any single piece of equipment.

  • Weekly water changes: 20 to 30 percent of the tank volume, replaced with temperature-matched, dechlorinated water. This controls nitrate accumulation and replenishes minerals. Larger tanks with lower bioload may need less frequent changes; smaller tanks or multi-axolotl setups may need more. Let your nitrate readings guide the schedule.
  • Weekly parameter testing: Ammonia, nitrite, nitrate, and pH at minimum. Record the results. Trends matter more than individual readings; a nitrate level creeping upward over weeks signals that your water-change schedule needs adjustment.
  • Filter maintenance: Rinse sponge filter media in removed tank water (never tap water, which kills beneficial bacteria) every 2 to 4 weeks, or when flow visibly decreases. For canister filters, clean mechanical media monthly and replace chemical media per manufacturer schedule. Never clean all biological media at once; stagger to preserve the bacterial colony.
  • Spot-cleaning: Remove uneaten food, waste, and dead plant material as you see it. A turkey baster is the simplest tool for targeted waste removal without disturbing the substrate or the axolotl.
  • Temperature monitoring: Check daily. A min/max thermometer shows overnight lows and daytime highs. Seasonal transitions (spring warming, fall cooling) are the periods when temperature drifts catch keepers off guard.

For a complete maintenance schedule covering daily, weekly, and monthly tasks, see the care guide and the water parameters guide.

Common setup mistakes and how to avoid them

Experienced keepers in the axolotl rescue and rehoming community see the same preventable mistakes repeatedly. Knowing these patterns before you start is more valuable than troubleshooting after something goes wrong.

Skipping the cycle. The number-one mistake. “I set up the tank yesterday and the water looks clear” is not cycling. Bacterial colonies take weeks to establish. There is no shortcut that eliminates the waiting period, though seeded media from an established tank can reduce it. Every axolotl placed into an uncycled tank is exposed to toxic ammonia and nitrite levels.

Using gravel. Gravel impaction is a surgical or fatal emergency. No gravel type, size, or brand is safe for axolotls. Bare bottom or fine sand only.

Oversized filter without flow control. A filter rated for 50 gallons on a 20-gallon tank produces current that causes chronic gill stress. Match filter capacity to tank size and always use a flow-control valve, baffle, or spray bar.

Placing the tank near a window. Direct sunlight raises water temperature and drives algae growth. A tank positioned in a south-facing window can swing 5 to 8 degrees Fahrenheit over a single sunny afternoon.

No cooling plan for summer. Keepers who set up tanks in winter discover the temperature problem in June. Plan cooling before you need it. A chiller purchased in advance costs less stress than an emergency fan setup while an axolotl is already heat-stressed.

Adding the axolotl too soon. Cycle first. Acclimate properly. Test daily for the first two weeks. Patience during setup prevents months of corrective intervention.

Frequently asked questions

Can I use tap water for my axolotl tank?

Yes, but only after treating it with a dechlorinator that neutralizes both chlorine and chloramine. Most municipal water supplies use one or both disinfectants, and both are directly toxic to amphibian skin and gills. Seachem Prime and API Tap Water Conditioner are widely used. Never add untreated tap water to the tank, even for small top-offs. Well water does not require dechlorination but should still be tested for pH, hardness, and any contaminants specific to your local geology.

How long does cycling take?

A fishless cycle using pure ammonia typically takes 4 to 8 weeks. The timeline depends on water temperature (bacterial growth is slower in the cool temperatures axolotls need), filter media surface area, and whether you seed the tank with media or bacteria from an established aquarium. Seeded media can reduce cycling time to 2 to 3 weeks in some cases. The cycle is complete when the tank consistently processes 2 ppm ammonia to 0 ppm ammonia and 0 ppm nitrite within 24 hours. The tank cycling guide linked above covers the full process.

Do axolotls need a heater or a ceramic heat emitter?

No. Axolotls are cold-water animals that need temperatures between 60 and 68 degrees Fahrenheit. A heater or ceramic heat emitter would push water above the safe range and create heat stress. The equipment concern for axolotls is cooling, not heating. If your room temperature drops below 60 degrees Fahrenheit consistently, a low-wattage aquarium heater set to 62 degrees Fahrenheit as a floor could prevent extreme cold, but this situation is uncommon in heated homes.

Can I set up an axolotl tank without a filter?

Technically possible but not recommended for any keeper, especially beginners. Without a filter, the nitrogen cycle has no reliable home for beneficial bacteria, ammonia and nitrite will accumulate between water changes, and you would need to perform very large, very frequent water changes (daily or every other day) to keep parameters safe. The cost of a sponge filter and air pump is under $30 and eliminates the single largest ongoing risk to the animal’s health. There is no practical reason to skip filtration.

What water parameters should I check before adding my axolotl?

Before the axolotl enters the water, confirm: ammonia at 0 ppm, nitrite at 0 ppm, nitrate below 20 ppm, pH between 6.5 and 8.0 (7.4 to 7.6 is ideal), and temperature between 60 and 68 degrees Fahrenheit. If any reading is outside these ranges, correct it before adding the animal. The water parameters guide linked in the maintenance section covers interpretation and correction in detail.
