Well, with the additiona of two 250w MH's my reef is now staying 79-83. I hate the 4 degree swing from night to day but it will have to do for now. I use to be 79-81.

What is everyone else at?

I also accidently forgot to hook back up a timer today and found that my MH's were on for over 10hours and the tank was at 86 when I got home. They are of course off now but I hope it hasn't streesed anyone out too much! Any input here from anyone?
