De Nitrate has a high surface area and supports a high density of bacteria. It is an economical, natural, porous material with a pore distribution.


The make-up of this filter medium promotes both aerobic nitrification within the first few millimetres of depth and anaerobic de-nitrification at the core.


Aside from the primary function of anaerobic nitrate removal, De Nitrate also has the limited capacity to trap nitrate.


De Nitrate removes nitrate the same way that reefs and live rocks do so and because water is forced through the porous De Nitrate, it is even more efficient.


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.

 


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 litres 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.

 


Doseage:


Each 500 ml of De Nitrate treats about 100–200 L, 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.
