Seachem

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. Great for both freshwater and saltwater aquariums. The material has a high surface area and supports a high density of bacteria. 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.

“Live” rocks or reef rocks remove nitrate by anaerobic denitrification. denitrate™ removes nitrate by the same process. Efficiency is magnified several folds by forcing the water to filter through the porous de*nitrate™. As with reef rock, anaerobic conditions are achieved by the porosity and the depletion of oxygen by the aerobic process at the surface. Excessive flow rates should, therefore, be avoided, as they may impede development of an adequate anaerobic environment to support denitrifying bacteria.

de*nitrate™ is also an excellent media for aerobic nitrification and it makes an ideal biological filter in drip trays, canister filters, sumps, or even box filters. At high flow rates (greater than 100 US gallons per hour), it will function solely as an aerobic filter. At slow flow rates (less than 50 US gallons per hour), it will function as both an aerobic filter and an anaerobic denitrifying filter.

Directions
For best results, de*nitrate™ should be placed to assure the flow of water through it, such as in a canister filter, chemical filtration module, or box filter. Flow rate should not exceed 200 L (50 US gallons) per hour. If higher flow rates are unavoidable, use Matrix™ or Pond Matrix™. It is best to rinse off dust before use. Once de*nitrate™ has been in use for several days, nitrate concentrations should start to fall and level off gradually at a concentration of about 4–5 mg/L as nitrate. As long as nitrate concentrations remain under control, the product is not exhausted. Each 500 mL of de*nitrate™ treats about 100–200 L (25–50 US gallons), depending on initial nitrate concentration and the current biological load. Enough should be used to remove nitrate at a rate at least as fast as the rate of formation. If very high nitrates are initially present, they should be brought down to less than 20 mg/L with water changes.

“Workin”

Put this in and after 4 days my Nitrates are down from 10ppm to 5ppm. So far so good, curious to see how low it goes.

“Works like it should”
4.5

I use this product even on my fish only set-ups. Works great to drop the nitrates and other chemicals out of water. I use in combo with chemi-pure elite and my chemistry is stable in all my set ups.

“Keeps fins in top shape”
5.0

Seachem's products are the most advanced in keeping fish in their best shape for showing and pleasure. Use and look at all their products; they have a terrific staff available through the old device called a telephone !!!!!!!!!!!!!!! Highly recommend their other buffers and ph regulators.

“Excellent product”
4.0

I have an overstocked 300 gallon tank, the SeaChem de*nitrate works very well in conjunction with water changes to keep my nitrates in the 30 ppm range. I would be much higher if it weren't for Seachem. Thanks.

“Very good product”
4.0

This product does actually work. I put a small bag in the sump area where the water must go through it to get to the return pump and its been working beautifully. Its slow... very slow actually. But my nitrates were around 80 ppm and now they are 50. Thats over a 4 day time span. Its continuing ...Read More

“Not working for me”
1.0

Did nothing to lower nitrates in my tank as I have done water changes every 3 days to help. I bought this product and it did nothing to lower nitrates. Nothing is going to beat water changes. BTW my water became cloudy (I got a very active Picasso lol) and it did not clear my water. I put a 10...Read More
