lfs sold wrong sump pump help

[LIBERTY]

I have a corner flow 110 tank 48x18x36 not a reef tank but it was on sale. It has 6 feet of head on the pump and sold me a little giant 2-mdq-sc not mush flow left.
and I'm getting a in line chiller 1 / 8HP TECO SeaChill Chiller TR10
Here is the question; What size pump do I need to make this right.

[LIBERTY]

forgot to say 3/4 down to sump 1/2 back to tank
anybody

With only 3/4" line down to the sump, you can't really move that much. Maybe a MAG9.5? Is your pump external or internal? Do you have a drilled tank, or is there an external overflow? What is your overflow rated for? More details will help get you answers...

tank is drilled overflow is rated at 700 gph pump is external
I have 2 koralia #3 in tank

In that case, then I would think a MAG7 or MAG9.5 would be ideal as a return pump. I have had good luck with Danner pumps, I had a pair of MAG12's that ran flawlessly for years.

If you do the 9.5, you will need a ballvalve on the output, probably.

mag pumps are internal or can it be external. I don't need to max it out so 7 will do 400 at 6 with 6 foot head
I'd like to stick with external type I think
And the chiller I can put it inline or do you think I'll need a different pump
sorry about all the Q

[Poseidon]

MAG Pumps can be ran either way, and as for the chiller, I would run it on a seperate pump, the flow rate for the chiller will have to be determined by the manufacturer, it may be to slow for to be ran inline with your return.
