ok so im lookin at gettin a 210 gallon from my LFS, and was planning on running a 55 gallon wet/dry sump and was wondering if it was better to run dual overflows or single?
Dual pumps is a very good point, and with two overflows, you can have one pump per return, which can work in your favor if you have two differently sized pumps.rallysman;1983897;1983897 said:go dual overflow, and don't worry about the canister. 55g is more than enough for a 210. I filtered a 300 off of a 55g sump and had a little room to grow.
However, I would suggest using 2 pumps just in case one fails.
