Review on 🐠 Fluval Clarify Bio - Optimal Aquarium Water Treatment by Leticia Wilhelmsen

Have been dealing with bio cloudiness in my tank for a while. The first one I ordered had a punctured foil seal under the lid so I got a replacement. In the meantime I've used the first one, with average results - the water became cloudy after use (as promised), but not much clearer afterwards. But with a fresh second it becomes much clearer - a noticeable improvement. So this material works with haze caused by biological issues, but it has to be fresh.
