my chiller went out a few weeks ago and I got up to 84 before I realized it. However I was able to cool down the room with A/C, and by opening up the top, putting in ice bags(don't put ice in your seawater), and blowing a fan over the top of the water I quickly got it back down to it's nl temp 79. Evaporative cooling will be your best friend, but if the ambient temp is 95, you're probably gonna need some ice too.
