I am debating on a return pump for my 90gallon tank. The tank is drilled for .75" return and a 1" drain that is supposed to handle 600gph.
I figure I am between a mag7 and mag9.5. Here are the specs...

The return will only be going from under the tank so that is about 5' maybe another foot or so under the tank to get to position. I plan to use flex tubing to minimize bending so there will be minimal pressure loss from that.
So really I am wondering if any has used or think a mag7 could be adequate? Even at 7' head it would still give me 4x turnover. I would really prefer to use the smallest adequate pump.
My other thought is that I may want to get my fuge flow from splitting some of the return off. I don't want to feed my fuge from the drain water because from reading I have done I think that is the dirtiest water and should go straight to the skimmer compartment. What kind of flow through the fuge would be good? (My fuge will serve purpose of growing macro and hopefully copepods.) The fuge will be 10-15 gallons depending on how much I cna reserve out of a 30g tank 36"x12"x16"
