Kent Marine Phosphate Sponge, 1-Quart
Sorry, this item is out of stock
Kent Marine Phosphate Sponge is not an algaecide, but a ceramic medium which will adsorb phosphates quickly (within hours) when placed directly in the water flow. Works in fresh and saltwater aquariums or ponds to bring about 1.0 ppm of phosphate or silicates down to less than 0.05 ppm in a 120- gallon tank for every dry quart of medium. For silicate to be removed, phosphates must first be removed. Beads are cracked to expose more surface area and increase efficiency. This product will not release soluble aluminum compounds into your aquarium, causing negative reactions from your inverts, as competing products may. Will also absorb moisture for use as an air dryer forozone, and can be renewed over and over in moisture removal service.
