Cleanwater Aquarium Filter Media
Cleanwater is a mixture of clay beads and special resins. It helps to reduce substances in the water which tend to promote the growth of undesirable algae. It absorbs phosphate, nitrite, and nitrate without removing important trace elements. The clay beads promote the settlement of beneficial cleansing bacteria. The aquarium water turns crystal clear, creating ideal conditions for fish and plants. Place the net bag into the last stage of your filter. Lasts two months.
