JB - Looks great.
I use a 40 gallon breeder with glass baffles for my prop tank. I push through about 1000-1200 GPH. I'm kind of on my second phase though. I didn't like egg crate in my system at all. Reason: Snails/crabs had a hard time navigating over it. So, now i just put my frags mounted to small flat rubble on the bare glass bottom. This system seems to be working better for me.
I'm curious as to how those 250 xm 20k will work. I keep hearing such mixed reviews. I currently suspend a 250 watt 6500 k iwaski 8" above the tank. My lights are on reverse cycle from the main tank. No over heating problems on my tank at this point, but it is -3 w/o windhchill today! Serousily, I plan to hit the system with 2 large bedroom type fans before summer.
