NT Labs Aquarium Tonic Salt 300g
Freshwater fish constantly regulate their internal salt concentration through a process called osmoregulation.
When fish become stressed or diseased this process becomes dysfunctional and fish begin to lose control of this salt regulation. NT Labs – Aquarium Tonic Salt provides osmotic support and assists with recovery from stress and disease.
Always test your water using Aquarium Lab test kits.

Used this salt after my betta showed signs of stress. Water parameters improved within a week. I noticed better color and activity. The instructions were clear and easy to follow.

Helped stabilize my community tank after a water change. Fish seemed more active and less lethargic. I still test water regularly, which is a good habit.

My goldfish had a sudden illness. After adding the tonic salt as recommended, the symptoms eased over 5 days. I now use it as a preventive measure during water changes.
