Sulfur Denitrator

Sulfur Reactors (denitrators) are used to effectively reduce nitrates in a closed aquarium system. The natural reduction of nitrate to nitrogen gas will only occur if there is a very low oxygen level area within your system which will allow anaerobic bacteria (thiobacillus denitrificans) to exist (in sufficient quantities) to handle the waste that is being produced by your tanks inhabitants such as within live rock or in a deep sand bed. Where this does not exist, it is necessary to create such an environment, and this is where the sulfur denitrators come in to play. Neither bio-pellets nor traditional nitrate reactors (alcohol) are maintenance free and without consequence. It’s their inadequacies that have led to the popularity of sulfur based de-nitrates. Sulphur nitrate reactors implement a process called autotrophic sulfur denitrification. This process has been used to remove excess nitrate from fresh drinking water for over 15 years. Bacteria (such as Thiobacillus denitrificans a
