i built one of these and it worked - the nitrates going in were about 20 (this was when i was having tank issues) and they came out as 0... The only problem was it could't process enough water to make a differance i have about 200 gallons of water and i used the highest rated eheim pump (not sure on gph rating) Denitrator was 2.5 feet tall had 75 feet of 1/4" coils and bioballs in the center chamber. The fastest i could get water through was a steady drip and it did not bring down my tanks nitrate at all. May have been beneficial on a smaller tank like 30 gallons or something.
