I thought that the Mazzei would just be used inline from my canister filter's output, so this is sounding much more complicated than I thought it was. I was first going to try this on the 20-Long in my kitchen, my "test" tank, but it sounds like a Mazzei is really intended for large tanks with more complex plumbing... And secondary/tertiary pumps, a flow or pressure gauge, and more?

Tom, on your 180 gallon starphire tank, I thought you just put the Mazzei inline on the output of the one Ocean Clear's return to the tank? Just plunked into the return flow, with nothing else.
