Lowering phosphates?

[calylove]

Ok so I've come to the conclusion that the brown growing in my tank is diatoms and that they will go away. Does it really have to do with phosphates? And if so how do I get rid of phosphate? Actually, what the hell are phosohates? Thanks for any help.

Phosphates are chemical compounds containing phosphorus. Phosphorus is a non-metallic element which is necessary for life and is found in rock as inorganic phosphates. As water runs over and through rocks it carries off small amounts of minerals such as calcium, magnesium, and phosphates. Inorganic phosphates are a plant nutrient and are taken in by plants with water and incorporated into organic phosphate compounds. Animals obtain their essential phosphorus from phosphates in water and plant material. Natural waters have a phosphorus concentration of approximately 0.02 parts per million (ppm) which is a limiting factor for plant growth. On the other hand, large concentrations of this nutrient can accelerate plant growth.
The use of RODI water will help in keeping phosphate levels low and under control.
