Anthony, I am setting up a single refugium tank, but want to split it up into two zones. One zone will be a sand bed and live rock, the other zone will be a chaeto ball if I can find some to buy. My fuge is a rubber tub, 52"X28"X24", my main tank is 180 gallon, and my sump is 50 gallon.

Is this dual zone a good idea, and how would you set it up? Which would be the first zone, and which the second? How big for each, how much flow.

Thanks!
