We most frequently encounter filamentous algae, is Flocculant effective against it too?

True, filamentous algae constitute the most frequent problem in pond water: they form long slimy clots and swimming in such an environment is far from enjoyable.
In this case, use our FLOCCULANTas prevention at the beginning of the season. This product will precipitate nearly all phosphorus from the water and the filamentous algae will lack nutrients for their growth.

Phosphorus is also removed from the water by SORBENT CFHa product serving as ongoing prevention. Held in a through-flow pad, the product consists of brown granules which adsorb (capture) phosphorus on their surface, thereby irreversibly removing it from water.

Once again, as a result, algae lack nutrients for their growth.
