Purigen™ is a premium synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%. Purigen™ controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen’s™ impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen™ darkens progressively as it exhausts, and is easily renewed by treating with bleach. Purigen™ is designed for both marine and freshwater use. 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. This product is sold by volume. Cited weight is minimal weight.

Renew™ is ideal for use in systems where phosphate released from all activated carbons poses a problem. Renew™ is also less aggressive than carbon, making it well suited for reefs and planted aquaria. It is also beneficial for use in soft water aquaria where the pH-raising property of many carbons is not an asset. Renew™ will remove organics and particulates in the sub-micron range; it will also help control ammonia, nitrates, and phosphates. This product is sold by volume. Cited weight is minimal weight.

HyperSorb™ is a synthetic adsorbent that outperforms all other blended synthetic media and carbons. It has exceptional organic removal capacity: it removes organic waste, toxic vapors and other pollutants. In freshwater it will help stabilize the ionic balance and will help control ammonia, nitrite, and nitrate. It is easily regenerated with household bleach. Marine and freshwater. This product is sold by volume. Cited weight is minimal weight.

Sizes: 100 mL (bagged), 250 mL, 500 mL, 1 L, 2L, 4 L, 20 L

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 bead-shaped 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.

CupriSorb™ is a powerful adsorbent of copper and heavy metals. CupriSorb™ will remove copper more rapidly and efficiently than carbon and is thus ideal for emergency copper removal. It extracts all types of copper from water and, if in continuous use, from the gravel/substrate bed as well. CupriSorb™ will allow maintenance of invertebrates in copper-treated tanks by removing copper leaching from substrates. This product is sold by volume. Cited weight is minimal weight..

SeaGel™ is a blend of MatrixCarbon™ and PhosGuard™. MatrixCarbon™ is an ultracapacity carbon for the removal of organic and color impurities. PhosGuard™ is a powerful remover of phosphate, silicate, toxic metals, and acids. Both components are bead shaped for optimum water flow characteristics and penetration. The components enhance each other and are ideal for reef and marine use. May also be used in freshwater that is not phosphate buffered. This product is sold by volume. Cited weight is minimal weight.
