Each very small powder particle has millions of nano size holes, which by ion exchange help absorb nitrates, phosphates and other pollutants in the water.  Its “pH Neutral” has no effect on waters pH and it maintains clear healthy clean water.  Activated by water Hydra Crystal immediately starts to electrically charge individual algae cells so that they clump together and sink to the bottom of the pond where either the filter system will clear them or if there is no filtration, they will decompose over time.
