temp in 55gal?

[metmike]

I have a 55gal reef with a 5.5gal sump and for a couple of months now my tank has stayed any where from 82 degres to 86 I took my heater out but it did not change the temp a chiller is not in my budget right now every thing seems fine but i was just wondering if this kind of temp could hurt any thing that i could not tell any info would be great thanks

82 actually isnt too bad, but i wouldnt go past 83..anyway, to keep your tank cool for now, buy a small fan and have it blow across the surface of your sump(you can also have one blowing at your lights)..Guarantee itll bring it down a few degrees..

86F is fine but the large temp fluctuation down to 82F is no good.
The fan suggestion is great, if you have a cover over the tank remove it. If that lowers the temp then that's great. If not then set your heaters for 85F so that the temperature doesn't fluctuate.
