I'm setting up a 105g Oceanic tank soon. I would like to know how Much GPH should my main return pump pump??(over-flow from tank into sump then back to tank w/ a spray bar or two) My told me Arill my tank so I did,and have a 1 1/4" bulkhead fitting at one corner of the tank
I think that the inside of BH fitting is only 1"??
How much will that flow?? B: He told me I'd be ok w/ a Little giant pump that is only rated at 180GPH w/0Now I heard on another BB that I should be pumping atleat 1000GPH

Does this sound right to you guys??? If this IS true do I have to have the main pump pump that much or can I say... pump 600-800GPH with the main pump then use power head in the take to gain the x-tra GPH needed??? Please help me I do have 1 lil giant in-line that rated @ 500GPH and 1 other thats rated @ 180GPH
