I now have the 2/175MH and 2/110VHO up and running over my tank. They look great however, I monitored the temp yesterday. The MH are on for a 7 hour period and the temp got up to 82.6. This morning when I got up it was at 78.9. Is this flucuation going to cause problems for me in the future? I was thinking of going for some sps in the near future but I obviously dont want them to die. What do you think?
