NT Labs AxoTonic is a balanced salt mixture designed to create optimal water conditions for axolotls, helping reduce the occurrence of fungal infections and supporting recovery. It adjusts the pH, KH and GH of tap or DI/RO water while providing essential trace elements for axolotl health and wellbeing.
By maintaining stable water chemistry, AxoTonic helps create a stress-free environment that promotes stronger immunity and overall vitality.
Calculate your aquarium volume in litres:
Length × Width × Height (cm) ÷ 1,000
(Or use the NT Labs dosage calculator for convenience.)
Test water hardness (GH) using NT Labs Hardness Test or Aquarium Lab Multi Test Kit. Dose rates depend on your GH result (see package for details).
Shake the bag thoroughly before use.
New aquariums: fill with water and add the full required dose directly.
Aquariums with axolotls: add the dose slowly over 5 days to avoid stress.
Water changes: calculate the volume of new water being added and dose only for that volume—not the entire aquarium.
