I understand that there is a piece missing, but when was the last time you took it apart and scrubbed it to remove built-up debris & algae? Mine tells me when it needs to be cleaned, because built-up debris always makes it shudder.

I don't understand how your tank could overflow without it. As for a fix I don't have an answer.

I agree. How does a powerhead not make a tank overflow?

Hello everyone, so sorry for the late reply on such an urgent post but i got it working.. i had to take it apart and clean it.. it turns out it wasn't missing a piece, i was just looking at the wrong video lol .. but anyways as for the tank overflowing without the powerhead, i dont know how that happens but all i know is that without the powerhead the water level in the sump starts getting lower, and the tank slightly higher. My only guess to this is that the powerhead pushes water into the overflow, so that the rate of water going into the sump is the same as the pump pushing back in. I dont know.

that is a disaster waiting to happen. i would advise addressing that ASAP. your tank/sump water levels should not change appreciably when turning powerheads on or off.

i have 2 MP40's in my tank. they can both be turned off as long as i wish without impacting water level.

that means your return pump is too strong for your overflow size. Has nothing to do with the mp40. smaller return pump or put a ball valve on your return to dial it back. as said above it is a disater waiting to happen
