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. This product is sold by volume.Cited weight is minimal weight.

MatrixCarbon™ is a truly unique activated carbon. It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density of macroporous binding sites. MatrixCarbon™ has a very low ash content as indicated by its minimal impact on pH. Even when added to distilled water, it does not raise pH above 7.0.While all carbons contain phosphate, regardless of false claims to the contrary, MatrixCarbon™ has the lowest detectable leachable phosphate content of all major carbon brands tested. MatrixCarbon™ outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorption, and duration of use.

PhosGuard™ rapidly removes phosphate and silicate from marine and freshwater aquaria. It is not recommended for phosphate buffered freshwater. PhosGuard™ is highly porous for high capacity and beadshaped for optimum water flow. It outperforms all competing products. 500 mL easily treats over 150 gallons. This product is sold by volume. Cited weight is minimal weight.
