Flatzboy and Beth, Thanks for the compliments. Ive seen your tank Beth and just love it. I have my hood hanging from the ceiling. I thought I would hate it but I love it like that. So easy to get to everything and no heat problems. It's a dual 250w 10k ushio mh, and dual 96w 03's pcs. With a biult in fan blowing air through the hood from one side to the other. I just recently put my lights on digital timers and I love it. My actinics come on at 9:30 am then the mh come on at 10:30 am and mh go off at 8:00pm then actinics at 9:00 pm and finally the moonlight comes on at 9:30 and goes off at 4:00am.
