SEACHEM DE-NITRATE 100ML BAGGED
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. 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. The primary mechanism of nitrate removal is anaerobic denitrification.
“Live” rocks or reef rocks remove nitrate by anaerobic denitrification. de-nitrate™ 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 within the core of the material.

FAQ
How does de-nitrate™ remove nitrate from aquarium water?
de-nitrate™ removes nitrate through anaerobic denitrification, which occurs in the core of the porous material. The process is enhanced when water flows through the material, creating anaerobic conditions that allow bacteria to convert nitrate into nitrogen gas.
Is de-nitrate™ effective in reducing nitrate levels in a reef tank?
Yes, de-nitrate™ is effective in reducing nitrate levels in reef tanks. It works similarly to live rocks by promoting anaerobic denitrification, especially when water is filtered through the porous structure.
Can de-nitrate™ be used in combination with other nitrate-removing products?

Gavin Hill –
I’ve used de-nitrate™ in my marine tank for three months now. Nitrate levels dropped significantly after adding it. The material is easy to install and fits well in my filter system. Water flow through it seems to enhance the denitrification process. No noticeable changes in water chemistry or fish behavior.

It works well in my 100-gallon reef tank. I noticed a steady decline in nitrate over time. The 100ml size is sufficient for a small to medium tank. I plan to add more when the current batch is used up.

After installing de-nitrate™, my nitrate readings dropped from 80 ppm to under 10 ppm in two weeks. The material is stable and doesn’t break down easily. I appreciate the natural approach to nitrate control without chemical additives.
