hey guys I've been try to find info on this but can't. i know that sulfur reactors work wonders in SW reef tanks to control Nitrates. wouldn't this be a great unit to install on FW stingray tanks if you want to cut down the water usage? correct me if I'm wrong or if this is something any of you have experience with. my system is running A1 with no problems at all but thought it would be interesting to be able to cut down the volume of water needed for my auto water changes. thanks
