Just like the subject says. I have a 90 gallon system with a Mag 12 return pump. I have two SCWD's in the return; one side of the SCWDs return through bhds in the back of the tank, and the other side goes over the top of the tank to the front glass, turn down, then point back towards the sides at a 45 degree angle.
At first, I thought it was the check valve, so I removed it. No such luck. I have my suspicions about the two return lines over the top of the tank, but once they fill with water, the larger bubbles dissipate, but the microbubbles don't. I'm thinking maybe the SCWD outputs and inputs have to be siliconed, although there are no leaks, I'm thinking they may be sucking air. Anyone have this problem with a SCWD in their system?
Thanks in advance!
