Seachem De Nitrate helps to remove the Nitrates , Nitrites , Ammonia and organics from your aquarium .
Seachem De Nitrate is a very economical , natural, porous material with a geometry that promotes aerobic nitrification on the first few mm of depth and then anaerobic denitrification at the core ( low oxygen level bacteria , this allows the bacteria to consume the nitrate out of the water column which aids nitrate reduction - must be used at under 200 litres per hour ) . Aerobic bacteria grows in water flow over 200 litres per hour , anaerobic grows in water flow under 200 litres per hour . If you are wanting to reduce nitrates and ammonia in an aquarium with a flow rate of >200l/hour please use Seachem Matrix
Seachem De Nitrate has a really high surface area which allows bacteria to grow in a low oxygen level of water . This aids in the reduction of the nitrate within your aquarium .
Seachem De Nitrate is best used in a low flow area of your aquarium , either within the filter box of an external filter ,a seperate media reactor or an internal filter that has a flow of under 200 litres per hour
500ml of Seachem De Nitrates 100-200L of water
