Do I need a chiller?

[johnyens]

Great advise guys thanks a lot!

I run 6 x T5's on my tank. Right now I have a fan accross the room blowing air in from outside. The tank is covered with a glass top so I may have to take that off on hot days. I hope my Blenny does go carpet surfing...

I already have an ATO so thats not an issue. I will try moving the fan closer today as it is suppose to get pretty hot. Right now temp is at 80.6 up from 80.2 earlier this morning.

I may just buy the chiller. We invest so much in our tanks it would be a shame to have it all die because of heat issues...

Thanks again to everyone for their advise.
