Although not normally a major problem for most fish, excess nitrate (NO3) in a reef aquarium can be very detrimental the health of corals and many other invertebrates. Aside from using a denitrator unit, a number of methods (i.e. the Vodka Method) and materials can be utilized to absorb or convert nitrate to a harmless substance. Here are some nitrate absorbing products which will help resolve high nitrate problems in saltwater aquarium and reef tank systems.

Manufactured by SeaChem, De-Nitrate removes nitrates, nitrites and ammonia. This product comes in loose form and must be contained in a mesh bag or in a filter chamber and placed in the water stream.
A blend of natural and synthetic ion-exchange resins that selectively remove ammonia, nitrite, and nitrate. In new aquariums, Nitra-Zorb controls the level of toxic ammonia and nitrite during initial development of the biological filter. In established aquariums, it helps control sudden surges in ammonia and nitrite caused by the addition of new fish, or anytime ammonia or nitrite is detected.

Instant Ocean Natural Nitrate Reducer is the easy solution for long-term reduction and control of aquarium nitrate levels. Patented formula promotes the natural denitrification process of converting nitrate into nitrogen gas.
Mangroves are an efficient method of removing nitrates, phosphates and other toxins from a saltwater (or freshwater) aquarium system. Once the plants are acclimated and installed in an aquarium system, they require little maintenance and can add another dimension to the aquarium experience.
With the Poly-Bio Filter Pad by Poly-Bio-Marine, Inc., water impurities like phosphate
, nitrate, copper, silicate, and even ammonia are absorbed. The pads can be regenerated by simple rinsing in saltwater (saltwater use can be regenerated by the reverse, rinsing in freshwater). Simply roll or cut the pad to any shape, place it inside a canister filter
or incorporate it into any type filtration system to easily remove troublesome elements in saltwater aquariums.
Purigen is a synthetic adsorbent, not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water. Purigen removes proteins, nitrites and nitrates, ammonia, and a broad spectrum of organics. Purigen darkens progressively as it exhausts, and is easily renewed by treating with household bleach.
