Phos-zorb removes all phosphate fast!!
Phosphate feeds algae blooms in Aquariums. Phos-zorb will reduce a
5.00 ppm reading of phosphate to 0 ppm in 2 days and the Algae
disappears. It will last for about 2 monthes or keep the Phosphate
level at 0 ppm. You need a phosphate test kit to know the level of
phosphate in your water.
