Review on 🐠 Fluval Biological Cleaner: Enhance Aquarium Health and Water Quality by Azizah Jefferson

Used that amount in a 5 gallon tank and the water is clearer and the live plants look pretty good! But I think it kills the snails - 2 days after adding it with a water change all the snails have started climbing to the top of the tank and some are swimming now. The three-anchor catfish also swims close to the bottom with its tail up and does not sit on the bottom. Beta seems unimpressed. Let's see what happens in the next few days.
