Fans get you pretty far, at least lowers a few degrees if you also manage the local humidity. Fans = faster evaporation = cooler water, but if you don't continue to cycle the air in your house to remove the excess humidity that builds up, the evaporation will slow down or stop. So you can probably get creative with fans to stay under the threshold of coral death, but it's nerve wracking. I did it for years myself. Frozen RODI bottles tossed in the sump are a good emergency measure! Have 4 ready, throw in 2 at a time, while the other 2 re-freeze. Repeat.I haven’t had to deal with summer heat yet and I’m a little worried because I cannot afford to buy a chiller for my 90 gallon and I don’t know what else I can do, my freshwater tanks usually go up to 84-85 degrees but I know corals cannot deal with that so basically I’m screwed so far
