its always way easier to heat stuff up than cool it off. one idea i have seen for a DIY chiller, is take airline tubing and create a siphon in it and have it run through a mini fridge. you can drill a small hole just big enough to fit the airline hose through. little mini fridges are really affordable now. but again, it will not work for tanks in different rooms.
NM too much work im putting the AC on next Wednesday I believe . Thank you for the suggestion though.
