well, here is what I ended up with. Got a 24g nano cube (tank only), bought an Orbit 2x40w PC. I won't be able to keep high light corals, but most things will be fine. I will see how it does for a time, at least through summer, then maybe upgrade to MH 150w. Your tank looks great! I can't wait to get my larger one up and going. My 12g is getting smaller it seems. Thanks for the info.
