Review on 🐠 Betta Water Conditioner - Mars Fishcare North America - 1.7 oz. by Diane Brown

We were new to Betta Fish, got our first and set up an aquarium. But two weeks later our fish were still lethargic. Mostly slept all day and hardly swam. Received today, replaced about half the water in the tank and applied conditioner to the water. It was the difference between day and night. We've seen more fish in a few hours than we've seen since we caught them. Very happy with this conditioner.
