Axolotl Water tools: what they help with

These tools manage the water your axolotl lives in: water change volumes, nitrogen cycle tracking, salinity and parameter checks. In an aquarium, water quality is everything. Most fish health problems start with ammonia, nitrite or temperature drifting out of range.

What to know about water quality for axolotls

Axolotls are fully aquatic and stay in larval form for life. They need cool water of 16-18C, no strong flow, and either bare bottom or fine sand, since gravel causes fatal impaction. Target humidity is around 80-100%.

Test before you change anything. Correcting a parameter quickly can stress fish more than the problem you were trying to fix.
