It’s crazy hot in my garage but I keep the temps in the low 80s by running a fan on each tank, plus two fans and portable evap cooler and the garage cracked 6” lolI lived in Phoenix for 42yrs and unless the garage is vented from the house AC it gets horribly hot out there, how are you able to keep the water temps in the acceptable range?
I'm in Northern Colorado and I've got a 75g in my garage (with a couch, big screen and creature comforts) with the temps around 76 and the humidity is around 50%. This is very manageable for my requirements of 78 for my tank. I often thought of setting up a man cave when I lived there but found it unfavorable.
But I can’t wait to get out of here
