It's Getting Hot In Here

[txreefer]

Okay, here is my new problem. My AC went out yesterday, and it will not be fixed until monday. (It is supposed to be in the 90's today and tomorrow, then it is going into the 70's). Anyway, my tank is now around 80 degrees. And it may get warmer yet. This morning I unplugged my MH to cut out that heat. So here are my questions:
1) If I leave the MH off for a couple of
days, but leave my actinic on, will it
hurt my corals - polyps, a couple of
hards, xenia, leather, mushrooms.
2) How hot can it actually get and still be
okay for the corals?
3) What can I do (without buying a chiller)
to keep the temp down for a few days?
Any and all help will be appreciated. I just started adding more corals this week, and I hate to loose them already.

most likely it will not hurt your coral, think about this, in the real tropical country i'm sure it rains 3 days in a row at least once a year..

i'm not sure about your corals, but there are plenty of things to do to keep the water temp down.
1) if you have a canopy open it up.
2) put a cheap little fan over the canopy blowing air over the water.
3) if the water gets high, float a couple bags of ice.
good luck
