My LFS started running a couple of them, and I think it IS a Ca reactor. He's been playing with one, and now runs it with bottom half sulpher, thin foam divider, top half Ca reactor media. There's an ORP probe in the top, and the ORP is controled by the output flow. It's putting Ca into the system, and dropping the Nitrates also. He's super horned up for these things, think's they're the cat's a$$. He says that once the Nitrates are down to 0, the output will be almost fully open, then gets opened all the way so the bacteria don't die, they may diminish, but continue to pull Nitrates as they're produced. AND the unit has an impact on Phosphates also, not huge, but noticeable.
