I’ve used this salt for several months now and noticed my fish are more active and their fins look healthier. It’s easy to measure and mixes well into the water. No side effects observed.

Good for preventing common fish diseases. I added it weekly during the transition to a new tank. My betta showed faster recovery after a minor injury.

The packaging is larger than the old version, which is a plus. My community tank has been more stable since I started using this salt regularly.

It works as expected, but I found it takes a bit of time to see visible results. Not a quick fix, but consistent use helps over time.
