Kent Phosphate Sponge
Kent's ceramic medium will adsorb phosphates quickly (within hours) when placed directly in the water flow. Works in Fresh & salt water aquariums to bring about 1.0 ppm of phosphates or silicates down to less than .05 ppm in a 120 gal tank for every dry quart of medium.
- 1 quart treats 120 gallons.
