Bhsgk- Awesome! I like how there are so many people in the same general area. I'd love to come checkout your 40B someday.
CichlidMan, I took the trim off because if you look at the first pictures you'll see white areas on the back between the trim and the glass. I tried to remove whatever the white stuff was with a razor and a putty knife, I couldn't remove it without taking the trim off and it would have bugged me everytime I looked at. I'll definitely try that, I need to redo the top part of the overflow anyways. The ball valve I have is a cheap Home Depot one but I've been reading about Cepex ball valves and they're suppose to be much better.
Benar- I think I know what you're talking about, I know the glass-holes overflows come with a top piece to quiet it down, I'm sure something like this would work for mine too but I might try what CichlidMan suggested. I actually saw a similar setup and was going to try it.
