I’ve used this salt for three months now and my fish have shown brighter colors. The gill function seems better too. Easy to measure and mix into the tank water. No issues so far.

Works well for my community tank. I add it after every water change. My goldfish seem more active and the water looks clearer. A simple but effective product.

Great value for the amount. The salt dissolves quickly and doesn’t leave any residue. My betta has been more energetic since I started using it regularly.
