can you tell me my friend about your DIY denitrificator ??......im on making one for me....but i have freshwater tank and i want to break the nitrate using real ecosystem......can you tell about yours please ??
There's a reef central link that should have tons of pics. I started one and never finished... basically a vertical 4"-6" PVC with a base and a cap. 2 holes on one side for the water to criculate with the pump and a hole at the bottom for the clean water to exist.. An air cap at the top.. as I remember
