Pond Algae, also known as Blanketweed, can spoil an appearance of a pond and can create a biological imbalance that could result in damaging plants and killing fish. This "string algae" can even block or clog up pond filter and pump systems, reducing their effectiveness and possibly damaging them. Using the correct treatment helps to stop the growth of Blanketweed. TAP No More Blanketweed Treatment is a fast acting treatment that has been developed with an infusion of all natural minerals, enzymes and additives. When this unique combination of chemicals is introduced into the pond, it will quickly and successfully work to combat the blanketweed and slowly rid the pond of this algae. The formula build up of the No More treatment has been designed to produce a low clouding effect which can sometimes be seen from other similar treatments. Any cloudiness in the pond will clear after a few days, resulting in clear water.
