Guess what the problem is... 

My reef tank is making all sorts of splashing noises into the overflow & gurgling noises from the return into the sump. It's like a toilet flushing. Pulled out the overflow pipe & cleaned out all the holes but it's still doing it. Hubby the pipefitter says it's fine. I know what my tank's supposed to sound like & IT'S NOT FINE! No sleep for me tonight.
The problem I had last night:
Can you figure out what solved it???
Getting warmer...The return pipe was below the water level in the sump. In other words the water level in the sump was too high.
Getting warmer...
BTW, that wouldn't happen. Mine is always below the water level of the sump.
