The right and left lateral ventricles are structures within the brain that contain cerebrospinal fluid, a clear, watery fluid that provides cushioning for the brain while also helping to circulate nutrients and remove waste.
Phosphates usually enter a pool in the form of Tri-Sodium Phosphate, or TSP. During shocking of the pool, or adding of enzymes, TSP is broken down into the tastiest algae food known - Ortho-Phosphate. In this free state, ortho-phosphate provides all types of algae with a good food source.
Regardless of how it happens, if phosphates are allowed to remain present in pool, spa, or pond water, they will be reduced to orthophosphates, which are the only form of phosphates that algae can digest. Orthophosphate levels should remain below 100-125 ppb (parts per billion).
