I have one. I'm not using it at the moment. It was ran on a saltwater set-up. It worked fine while I was using it. I have the small for 20-55g tanks.
I was using 80 proof vodka as the nutrient source. It seems to work like a coil denitrator that you feed and is a little more stable. You absolutely have to also dose a buffer to keep your PH stable while using it.
Edit: It lowers PH greatly. I ran it in saltwater and it lowered my PH below 7.0. I had to run a buffer to keep it at 8.0-8.2. I also had to buffer weekly.
