Serenity Green Water Destroyer Block 20g
The Serenity Green Water Destroyer Block effectively controls most algae common to freshwater aquariums. The product kills growing algae and prevents algae from recurring. The flocculent in the block will then bind any floating dead algae or suspended particles causing them to sink to the bottom, where they can be siphoned of with ease or broken down by naturally occurring bacteria. Suitable for Frogs and Turtles.
