Thanks, that's what I thought too. If you read the "DIY" instructions that Caribsea puts out though, they just have it as a single-pass basis and it sort of sounded like that's how Pansy-Paws does it too (I could be reading it wrong?). I guess that way works too, but to me anything that requires contact time is always better to have it on a recirculating basis.
Well sounds like I'm set then .. I just need some media. I'm gonna have this online within a couple of days (just as soon as I can get my hands on some media!).
