Well, I will go so far as to say your LFS guy is an idoit!!!!!
CPR's are one of the better overflows (IMO) I have the CPR CS 100
I also run a Mag 9.5 and a Mag 5 as my return pumps (I have a 58 gallon)
The one comment I will make, is if you have not opened your overflow box yet, to exchange it for the 100 because it will not be fast enough to keep up with the return pump you have. You will have to throttle the pump back with a ball valve....not that great for the pump and could generate excess heat in your system. If not, it will work. ..I do have one of mine throttled back a bit.
I have not had my overflow leak at all, and my water level stays perfect in my display tank. You do need the Aqualifter pump to attach to the small hole in the top of the overflow. It draws out any air that gets into it and keeps it running efficiently.
Lights sound perfect to me! I have 175 W MH and 96W X 2 VHO on mine.
You are doing just fine with your research, sounds like! No worries!!!
