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 of with ease or broken down by naturally occurring bacteria.
Use one segment of the block per 20Lt of water.
Best used when green patches or green water appear in the aquarium.
Block can be used as a preventative
The block will slowly dissolve over 7-14 days depending on water conditions and rate of flow
Repeat process if green patches or green water appear in the future.
