I have a 33 gal
long tank with a 20gal long sump. In the sump I am running a Mag7 submersible pump, and I have an overflow box. Both the intake and output lines are 3/4" PVC
and both have Ball valves to fine tune the flow.
The problem is that the Mag7 is pumping water to the tank faster then the input can feed it. So to combat that I closed the output valve a bit to slow the water down.
What can I do to combat this problem. I don't want to restrict the flow and strain the pump. So should I add a tee with a valve and redirect some water back into the sump?
Any suggestions are appreciated.
