I need help setting up my new 120 gal tank.
I'm having trouble setting up my new 120 gallons tank. I was wondering if anyone can help me with some issues.
The tank is drilled on the side with one 1" over flow bulk head and a 3/4" return line.
The over flow is making a loud siphon noise so I put and airline tubing in it to vent it and works but the problem is that water flow drops and the the sump pump dries out in wet/dry filter. I installed a valve in air tubing to reduce the air venting and still can't find the right adjustment.
It either make a loud noise at the over flow or at the pump when it is dry.
