So Ive had my DIY denitrator on for a week. Actually I had it on longer with just seachem matrix and no sulfur. I was hoping to speed up the bacterial development. I didnt have high nitrates to begin with. About 5-10ppm. My denitrator has been on 1 drop per second since setting it up. My tank nitratetested today as 0 or undetectable.
So I guess Ill leave it at 1 drop a second.
No clogging yet, Im using a quiet one 1200 pump for recirculating and had to put a foam cover near the top because the recirculation was strong enough to make it look like a phosban reactor where the media was tumbling. The one drop a second has been pretty steady using a needle valve on the output.
