Phosphorus 101: What It Is, Why It Matters, and How to Control It

Phosphorus is a naturally occurring element found in soil, sediment, and organic material. In aquatic systems, it plays a crucial role in the growth of plants and algae. While phosphorus is essential to many biological functions, elevated levels in water bodies can contribute to nutrient imbalances over time.

One of the most bioavailable forms of phosphorus is orthophosphate, which can be readily taken up by algae and aquatic plants. This form often enters water bodies through runoff containing fertilizers, decaying organic matter, or internal loading from sediment. Once present, orthophosphate can support the growth of algae and contribute to the broader process of eutrophication.

Managing phosphorus levels typically involves identifying the sources and applying treatments that can reduce its availability. Algae Armor is composed of a mineral blend of iron oxides and zeolites, which chemically bind with orthophosphate in the water. This process forms insoluble particles that settle out of the water column. Learn more about Algae Armor here.
