Seachem de*nitrate 500ml

de*nitrate removes nitrates, nitrites, ammonia, and organics from both fresh and marine water. The high porosity of de*nitrate supports the proliferation of both aerobic and anaerobic bacteria that further remove these toxic aquarium byproducts.

Even when exhausted as an organic adsorbent, de*nitrate continues to be an excellent support for the biological filter and does not have to be removed.
