Hi all, long time lurker and hobbyist. I've been in the saltwater hobby for years now but don't want anyone to think I know what I'm doing ¯\_(ツ)_/¯ I currently have a 150 gallon (4ft long, 30 inch deep)- It's a mixed reef. Lots of Zoa's, softies, mushrooms, a few birds nests and lps a whole bunch of nems and critters. I have a good amount of super fat fish- I think I'm unusual in the reef hobby because after years of it I find myself more obsessed with interesting fish than coral [emoji4]. Anyway, I'm curious how people keep their tanks cool here in the Pacific Northwest. In years past when it was getting too hot out I'd float ice packs in my sump and run fans over the water surface to keep evaporation up- I've had some hot days and stressed animals before but don't think I've ever lost anything to heat. That said it seems like we are getting more and more extreme in our seasons here and I'm considering something like a chiller. My house doesn't have AC so controlling ambient temperature is pretty basic (fans, shades, etc.) Thoughts?
