Has anyone tried it? I was reading on it from Melevsreef site for nitrate control. As of late I've seen my nitrates increase. I think due to some bad water I had gotten with a pretty high TDS. Ive changed 30 gallons of water a couple days ago with aquavitro salinity with 001 TDS rodi water. hope this will help bring them back down to safe levels. I'm also using red sea test kits as well.
