We just got our 55 gallon on a test run w/ FW. The overflow w/ pre filter
makes quite a racket.
Any suggestions for quieting the overflow drain. I'm pushing 1100 gal/hr
through the return jets at top speed. I have slowed it a little but still
noisy.
Should I lower my water level? Slow it down more? How fast should it be
flowing down to my sump (10 gallon)?

Any suggestions appreciated.
Thanx.

Mark and A
