AquaClearer™, S.A.B.™, and EcoBlast™ from Aquascape Designs do not directly treat algae and string algae. These excellent pond bacteria products eliminate excess nutrients from your pond water. Excess nutrients if not eliminated would feed and nourish algae and string algae and thereby allow the spread of both throughout your pond, stream, and waterfalls. Eliminating excess nutrients, their causes, and creating an environment to promote the growth of beneficial bacteria are the main objectives to creating a clean, clear, and healthy pond.
