How hot is too hot

[Vagabond]

Just a thought here Danny,

Home Depot sells small, Maytag, in window air conditioning units for around $179.00 which will cool off a room about 10 x 15. don't know how big the room your tank is in, but if you are really concerned this might be an option. A second benefit to this is that you get to enjoy a cooler room as well as your fish and corals!
