Phosphorous (as phosphate) can be introduced to aquaria through feed, decaying plant and animal waste, and even tap water, so it can quickly become so abundant that it becomes a nuisance. Phosphate is a driving factor in excess algae growth, so it is important to keep levels as close to zero as possible.
