Hi I am setting up a refugium on my reef tank for this I am using a 24" by 12" by 15 inch tank the problm is I only want a low waterflow though the refugium but in order to get the water from the main tank into it it has to be pumped up 2 foot. Now while ideally a power head would be used fo this. Because of the heght needed I doubt any powerhead would do it.
So this leaves me with canister filters (without media) now all these seem to have too high a flow rate for my needs so I have two questions.
1: would turning the taps down to control the flow on a full time basis damage the filter or have any negitive side effects you can think of.
2: what is the smallest canister filter on sale. I only want it as a pump the only other option I can think of is a pond pump but do not want to use a pond pump in my reef as it would look ugly if seen and take up space even if not seen.
Refugium will use overflow to return water so that isn't a problem also intending to silicone a piece of vented perspex in the tank all way across the back sealing off about 2 inch and a piece of non vented cutting that in half. So the water will go in on the left and come out the right but will be forced to go though all the refugium to get out. The sealed off areas will be used for my heater and as a refuge for corepods. Main area will eventully contain dwarf seahorses. For this reason the water flow in the main area should be quite low. I would welcome any comments or ideas you may have.
