drain pipe purging

[bryanb85]

Hello everyone, I'm new to this amazing hobby and have ran into my first problem. My drain pipe sounds like a flushing toilet! Water level increases to the factory holes then the water rushes in, fills back up and starts all over again. This is loud and annoying. Please if anyone has solved this problem, help me out, PLEASE!

Slow down the water flow from the pump, you are pushing more water in than the drain can effectively drain out. Either use a smaller pump or place a valve on the return line to adjust the flow until the flushing stops.

I will definitely try the ball valve. im pushing 977 gph as of now.

How far is your drain pipe below the water line?

Slow it down, my friends tank did the exact same thing very disconcerting to watch.

+1 on the valves. Mine was really loud until I rigged it up.
