What is Phosphate (P-PO4)?

In nature a true Phosphorus cycle exists. Phosphate is an important plant fertilizer that stimulates plant growth at very low concentrations. The Phosphate level in unpolluted natural waters is always very low, and Plants use so much that there is always a demand for it.

Phosphate In The Aquarium:

In the aquarium, the fish density is much higher than in nature. In most aquariums the plant growth is insufficient to use up all the Phosphate that is added with feeding, therefore it accumulates in the water. This leads to several undesirable effects, in particular blue, green and hair algae find favorable conditions and grow very fast. Marine invertebrates like corals may loose their zooxanthellae, (tiny brown algae that live in the tissue of invertebrates leading to degeneration and eventually to the death of these sensitive animals.

A successful coral reef aquarium depends on how well you maintain the water parameters which are the key to a stable coral environment. Using Red Sea test kits will allow you to accurately measure these levels and guide you on your path to reefing success.
