SeaChem de Nitrate - 2 Litre
de*nitrate is a high porosity filtration product for the removal and control of nitrate in marine and freshwater aquaria by anaerobic denitrification.
It is a porous inorganic solid about 4 mm in diameter. It can be used in a canister filter at slow flow rates or even on the tank bottom as a "live' substrate.
It does not require a special denitrifying filter or special culture feedings. It is also helpful in controlling nitrite and ammonia.
The surface area characteristics of de*nitrate are similar to Matrix, making de*nitrate an effective support for the biological filter.
Each liter treats up to 100 gallons.
Marine or freshwater use.
