    Re: Return pump for a 90g AGA Tank

    I have a Mag 7 on my 65 gal. How high is the head that the pump has to return? Is this return pump going to be a main contributor to your circulation in the tank or just to bring water down to your sump with your skimmer? If that is the case you don't really need to have more gph than what your skimmer can do. Save the $50 and get a maxijet 1200 for inside your tank.

    The return will be the main flow, with a Mag7 attached to a spray bar behind the rock work. Its 4 foot of rise from the sump to the top of the tank.

    Then I would go with the Mag 9. It has a larger diameter output as well. I have a Mag 7 pumping up 5 feet and I should have got a Mag 9.

    got the Mag9 put a ball valve on it, that is one strong pump. Should have done that the first time.

    MAG 12! I just set mine up on my 90g with sump and it works great. I put a T fitting and gate valve with PVC back to the sump right off the pump just in case it was to much power. All I did was open the gate valve first completely then slowly close it so all the water went up the returns, no probs! If you want to check it out let me know. 8)
