It has a grain size of approximately 0.5–1 cm (Reef Reactor™ Lg is 1 - 3 cm). de*nitrate™ works best if it is the only media used in the reactor other than a sponge filter. Obviously, the latter would be the simpler method. Reef Reactor™ is a high-purity source of aragonite, which supplies all important elements for optimal ionic balance and robust coral growth and coloration in reef aquaria. I've got to get my nitrates down! Seachem Laboratories Denitrate de*nitrate™ is an economical, natural, porous material with a pore distribution and geometry that promotes both aerobic nitrification within the first few millimeters of depth and anaerobic denitrification at the core. Seachem De-nitrate; This brand comes with high porosity that is especially adept at supporting the reproduction of anaerobic and aerobic bacteria that further eliminate these lethal tank byproducts.

Am considering adding denitrate to my sump and am wondering if it would be best to put it in a reactor with very slow flow, or to put it in a bag in the sump with little or no flow, to act much like a deep sand bed. Although de nitrate™ has capacity to trap nitrate, this, as with other nitrate retaining materials, such as certain zeolites and synthetic resins, is quite limited and the primary mechanism of nitrate removal is anaerobic. I set up this little system using Seachem De*nitrate, two fishes 150 reactor, a simple fountain pump rated @ 63gph, a dc motor control circuit to adjust the speed of the pump, and a dc power supply. I use a large media reactor by Avast that holds 4 liters and use a ball valve over half closed in front of it to throttle the flow. “Live” rocks or reef rocks remove nitrate by anaerobic denitrification. Although de*nitrate™ has capacity to trap nitrate, this, as with other nitrate retaining materials, such as certain zeolites and synthetic resins, is quite limited and the primary mechanism of nitrate removal is anaerobic. Seachem de nitrate™ Removes nitrates, nitrites, ammonia, and organics High porosity biological media Pore size well suited for anaerobic bacteria No danger of hydrogen sulfide production as with sulfur based media Overview de nitrate™ is an economical, natural, porous material with a pore distribution and geometry that Supports denitrifying bacteria in a nitrate reactor. Matrix is a highly porous media designed to provide exceptionally efficient bio filtration for single site reactor of ammonia, nitrite, and nitrate from freshwater, marine, and reef aquaria. The thing was simple to hook up and is working like a champ! Seachem Matrix Bio Nitrate Reactor Media 1 Liter.
