So i finally finished my DIY sump, got it all hooked up to the return piping, and did a test run. Roughly 20gal sump, in to a 55 gal main, with a mag 7 return pump. The problem is that my mag is pumping the water so fast that it drains the return section, causing it to suck up air and fill the tank with bubbles. I have a ball valve on it, and i have to close it pretty much halfway to slow the pump down enough so it doesn't suck all the water. Is this because of my overflow not flowing fast enough? It's rated for tanks 75-100 gal. It drains in to a 1" bulkhead. I figured this would be good enough as i have a 55gal. Anything i can do to try fix this, aside from closing the valve? Is my overflow just not able to keep up?
Another quick question. How much pressure am i losing with this setup on my return piping? Floor to top of tank is 4', and i pump up 2' before i tee it off. It runs to the left and right of the tank, with 4 "arms" that then pump up the final 2' to the tank. Would i have been better off just sending the water straight up the 4', splitting with the tee, and then put my returns in? Only during my test run i realized that pumping up 2' on 4 return arms totally kills my pressure...but would it make that much of a difference that i should redo my piping?
