API Aquarium Salt
API® Aquarium Salt is made from evaporated sea salt and is designed to support fish health in your aquarium.
It improves gill function, helping fish breathe more efficiently. The salt provides essential electrolytes that support peak coloration and overall vitality.
Electrolytes can be lost during partial water changes, so regular supplementation with API Aquarium Salt is recommended to maintain optimal water conditions.

My betta has been much more active since I started using API Aquarium Salt. The colors have brightened and the fish seems healthier. I add it every 4 weeks after water changes.

Works well for my community tank. The fish are more energetic and the water feels more balanced. I noticed a difference in their coloration after a few weeks.

I’ve used this salt for over a year and haven’t had any issues. My goldfish are more active and the gills look healthier. Easy to measure and mix.
