Did not work that great for me I have an extremely high bio load. Is bifar hands down the best Thing I had to reduce nitrate is a sulfur denitateor, second is pothos. For the record I have a continuous water drip Algae scrubbers pathos, sulfur denitateor . If you get a very good parasolic pump The sulfur denitrator is just about maintenance free when you get it going
Do you have a link to a sulfur denitrater or which one do you use? I've done some investigating on them in the past for anarobic denitrification and I heard good things about the AquaMaxx TS-3 but BRS never has it in stock.
