well after some leaks and breakage of the egg crate inside holding the sulfur in place had to take mine off line.. nitrates in the tank back up to 80ppm.. YEA!!! anyway.. so i am goign to redo some things.. first.. wondering if i need the second chamber of arm.. I have a taller peice of 6" od acrylic i was thinking of using and making one really tall reactor and adding as much sulfur as possible.. the lowest i ever got mine was to around 15ppm.. which was nice.. i still had issues with gas build up with the two chamber.. if i do one chamber with the gas vent/output at the same spot i can keep up on the gas venting and can smell the rotten egg smell if i ever get one.. sound like an ok plan??? I can always add a second chamber later.. just need to get more sulfur.. and bio matrix.. I think the new chamber i have is like 6" taller.. so like 30" instead of 24" that should be a bit more media..
Black71gp.........Yep your on the right track as the only way I finally got 0 ppm Nitrate..that's right ZERO :rollface: :rollface: was with more sulfur, actually what I did was make a second reactor ( a 3rd really as I'm still using the 2nd for ARM) and filled this completly with sulfur and within a few weeks I was @ 0.00 ppm Nitrate and the tank is still @ 0 hard to belive but true. After obtaining 0, I removed the 3rd reactor completly form the system and just recently I got the dreaded H2S SMELL so I removed approx. 1/2 the sulfur just the other day and I'm recycling the unit as we speak.
I'm not sure what u mean by " if I keep the gas vent value in the same spot " ??? and are u making a complete new unit and if so why not run the ARM reactor as they do raise the pH, ever so slightly, but none the less it works, other than that it sounds like a plan to me.
