how hot is too hot

My home AC isn't working right house won't cool below 80 and my tank temp has been 82-83 for for the past 3 weeks how long can my corals and fish take that temp till things start dying? also what is the maximum temp a reef can take for a short time?

 

Matt up until I got LEDS, my tank would stay that hot all summer with no ill effects. I think what you want to be more careful of are large swings.

 

I think you'll be fine Matt. After tomorrow the heat wave is breaking, so I wouldn't worry. My tank runs that high with no ill effects most of the summer.

 

I bought some USB fans at target to blow across water to cool down tank and it works. You may try that, but 83 84 degrees is fine.

 

Cool I just need to get through this summer and ill buy a much bigger AC
