Thanx!
I'm going to try the Durso standpipe first. It looks like a good design
also.
Anything better will make my wife happy.

Mark,

Running freshwater versus sal****er is very different. Plus after two
weeks,
the plumbing will develop a slime coating that will help a bunch.
Finally,
remove the sponge filter because it is a trap for floating debris and a
nitrate
creater.

If you still deal with noise, do a search for "stockman standpipe"

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.
