I’ve used this salt for three months now and my guppies seem more active and healthier. The instructions were clear and easy to follow. I added it during water changes and noticed a better water clarity over time.

Works well for my community tank. I added it once a month during water changes. My fish stayed active and didn’t show signs of stress. Just make sure not to use it with betta fish.
