Wholly crap Fred, just waiting by the comp for responses eh?
I guess that's the only excitement us married guys get nowadays huh?
I have no experience with a BM and have no idea how it works (I don't even know if it's in sump?) however a recirculating skimmer is the most efficient skimmer you can get. In sump wastes alot of the pump's energy sucking in the water and getting it into the skimmer body, and then uses the remaining energy to churn bubbles. Recirculating doesn't waste any energy getting water into the skimmer, and focuses 100% on making bubbles.
About noise, when you have the cabinet doors closed, you can't hear a thing. My main problem was the overflow noise (as I didn't use a standpipe), but if you can get the standpipe going with the corner overflow then you'll be laughin.
How is everything else going? Did you get everything setup? I assume you had to change the plumbing as we cut off the under the cabinet piping.
