Remove filamentous pond algae with Aqua Doc

FILAMENTOUS ALGAE

Single algae cells that form long visible chains, threads, or filaments. Starts growing along the bottom in shallow water, or attached to structures in the water. Gives off oxygen that becomes entrapped in the mat of strands causing it to rise to the surface. Often a persistent problem because it reproduces by plant fragments, spores and cell division
