Controlling string algae in you pond can be done by using String Algae Buster extreme and Ecoblast. These pond products are formulated to help reduce watergarden maintenance and promote the growth of beneficial bacteria and enzymes. String Algae Buster will assist in the breakdown and reduction of string algae in the stream, waterfalls and pond. String Algae Buster Extreme works by adjusting the micro-nutrients in the water of the pond resulting in conditions that are beneficial for good pond water quality and clarity. SAB will not harm pond fish or plants or disrupt the balance of the watergarden ecosystem. Also consider EcoBlast by Aquascape Designs. EcoBlast quickly breaks down pond algae in the waterfall, stream and in the pond. Use EcoBlast for spot treatment of bad string algae areas and SAB for long term control. EcoBlast by Aquascape Designs is not temperature sensitive so it can be used in cooler fall and winter months. Directions: Do not add String Algae Buster directly to your pond! Fill a small bucket with warm water. Add one tablespoon of String algae buster extreme to the bucket for every 100 gallons of water in the pond. Stir the mixture until the SAB has dissolved this will make a white/brownish mixture. The mixture can then be spread in the water around the edges of pond and in the stream. The water may become cloudy immediately after the mixture is added to the pond. This is normal and should clear up within 24-48 hours. The pond should be treated 2-3 times during the first month or once every 10-14 days. SAB should be added to the pond once a month every month thereafter. S.A.B.
