I think that my filtration is inadequate, and I don't want to add any live rock to my tank. I've been considering buying a sump for my 42 gallon hex tank, but I haven't been finding any good deals until today. I found a complete setup for a really good price, but there is a problem... it's for a 100-150 gallon tank, and I have a 42 gallon tank. Is this a problem?
My concern is that the siphon in the overflow box will run dry. The setup has a double outlet overflow box (don't know how many gph) and a Rio 2100 for the return. I'm concerned that with as little water as I have in my tank and as wimpy of a pump as that is the siphons will run dry. I'm new to sumps, though, so I thought I'd check with you guys.
EDIT - I forgot to mention that the drain hoses on the overflow are 1 1/4". I don't know if you can figure how the gph based on that, but that's the diameter of the two drain hoses.
