Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants should I do something about FA?

Adam, goal of Removal was to reduce the amount of FA that needed to be killed and thus less dead to sink, decay and add nutrients to grow more plants. In a pond that is to get a bloom removal is less important. If the algae is dead it will not regrow if it can't get light due to a new green water bloom. In clear water more FA will regrow due to algal spores or those filaments that did not get killed by the herbicide - there are always a few viable filaments 'around'. Nutrients from the slow decay of dead FA should theoretically assist the nutrients from fertilizaion for the bloom. Large amounts of decaying FA can consume lot of DO and in warm water (70F+) stress fish to the point some die due to DO loss.
