Denitrification Media

[Cal_stir]

I've been running a diy sulphur denitrator on my reef tank for 18 months, no problems. I clean the media, orp probe and reactor @ every 6 months, takes about an hour, I use an orp for control, and the recirc pump pressure for effluent flow, the controller uses a solenoid to increase the drip rate, the effluent passes through a TLF reactor filled with ARM calcium reactor media to raise the ph, my nitrates are less than 1 ppm in a heavily stocked well fed tank. I won't reef without it.
