Absorb phosphates quickly from your water.
Kent Marine phosphate sponge is a ceramic media that provides a quick and effective method of removing phosphates from your water. The media absorbs phosphates and silicates, trapping them inside. It can be used in marine and freshwater systems, including koi ponds and recirculating aquaculture systems.
One quart (650 g) of Kent phosphate sponge media will reduce 1.0 ppm phosphates or silicates to less than .5 ppm in 120 gallons of water. The particle size is 2 mm to 5 mm and can be retained using an 800-micron or smaller mesh bag or a canister filter. A 5-gallon container treats 2,500 gallons of water. The phosphate sponge media can be regenerated for reuse several times in a household oven. Use regularly to keep phosphate levels low. Made in the USA.
