SEACHEM DE NITRATE TREATMENT
denitrate™ 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. The material has a high surface area and supports a high density of bacteria. Although denitrate™ 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.

FAQ
How does denitrate™ remove nitrate from the water?
denitrate™ removes nitrate through anaerobic denitrification at its core, with aerobic nitrification occurring in the outer layers. The high surface area supports a dense bacterial population that facilitates the conversion of nitrate into nitrogen gas.
Is denitrate™ effective in reducing nitrate levels in aquariums?
Yes, denitrate™ is effective in reducing nitrate levels by promoting anaerobic denitrification. It works best when used in conjunction with proper water flow and maintenance routines.
Can denitrate™ be used in both freshwater and saltwater aquariums?

I’ve used denitrate™ in my freshwater tank for three months. Nitrate levels dropped from 120 ppm to under 20 ppm. The material is easy to add and maintain. No visible changes in water clarity or fish behavior.
Elizabeth Rutherford –
It works well in a planted tank. After two months, nitrate levels were significantly lower. I noticed a slight color change in the substrate, but it didn’t affect the tank’s health.
Isaac Gill –
Great product for reducing nitrate buildup. Installed it in my 55-gallon tank and saw a noticeable drop in nitrate after one month. The material stays stable and doesn’t break down easily.
