Green Water Destroyer Aquarium Algae Block 20g

The Serenity Green Water Destroyer Block for Aquariums effectively controls most algae common to freshwater aquariums and ornamental fish ponds. 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 off with ease or broken down by naturally occurring bacteria.

How to Use: To control algae, add one piece per 20L or use one complete block per 120L of Aquarium water. This block is best used as a preventative or when algae first appears or after cleaning an algae infested tank. The block will dissolve over 7-14 days depending on water conditions and rate of flow from filter. If possible control the amount of sunlight or artificial light to reduce the growth of algae. Repeat only when algae reappear.
