Water parameters
Stable water saves lives.
Axolotls absorb dissolved substances through their skin and gills. A cycled aquarium, repeatable testing, and small corrections protect them better than chasing perfect numbers.
Measure what matters
Know the numbers and the trend.
Record results so a small change is visible before it becomes an emergency. These targets summarize the existing Axolotls.com care standard.
| Measure | Working target | Why it matters |
|---|---|---|
| Temperature | 60-64 F (15-18 C) | Supports oxygenation and reduces heat stress. |
| Ammonia | 0 ppm | Any measurable amount can damage skin and gills. |
| Nitrite | 0 ppm | Nitrite interferes with healthy respiration. |
| Nitrate | Below 20 ppm | Lower levels reduce chronic stress. |
| pH | Stable, commonly 6.8-7.6 | Sudden change is often more harmful than a steady value. |
Before the animal arrives
Complete the nitrogen cycle.
Waste becomes toxic ammonia in an uncycled aquarium. Beneficial bacteria convert ammonia to nitrite and then to nitrate, which is controlled through maintenance and water changes.
Cycle without the axolotl
Use an appropriate ammonia source and confirm that the biological filter can process it before livestock enters the aquarium.
Test the full pathway
A tank is not ready because water looks clear. Measure ammonia, nitrite, nitrate, and pH with a liquid test kit.
Protect the filter
Keep biological media wet and avoid replacing all filter media at once. The bacterial colony lives on surfaces.
Weekly rhythm
Make maintenance predictable.
Test weekly, remove waste, and perform partial water changes with conditioned, temperature-matched water. Test immediately after appetite, gill position, buoyancy, or activity changes.
Change part of the water
A typical routine uses measured partial changes rather than large reactive swings.
Condition tap water
Neutralize chlorine or chloramine before new water reaches the animal or biological filter.
Correct causes
If a reading is unsafe, stabilize the animal and identify the source instead of repeatedly dosing toward a number.
