Yeah, so our ac is broke, and my tank is getting kinda up there in temperature. How high can it go without killing my fish and how can i keep it cool?
It depends on the fish. Get some ice or freeze some plastic soda bottles and place that in the tank water to cool it down. If you are using ice, place the ice in a ziplock bag so that no untreated water doesn't gets into your tank. If you have a sump...that's a good place to place the ice bottle or bag.
For a longer solution get a clip-on fan and blow that over the water. Evaporation will cool your tank. You will have to keep your eye on the tanks water level and refill will RO/DI water if it's a SW tank or treated water for a SW tank. I hope this helps.
