Cal-flow (sp)
PVC to sump/wet-dry (which is best)
Sump/Refugium or Wet/Dry (again, which is best) I assume that you're doing a reef tank. If that's the case, I'm pretty sure a wet/dry would not be a good choice.
Return pump (i know it has to match the GPH of the drain)
What else? In tank power heads or closed loop? Decide now or forever hold your peace.
Everything IMO, lol.
