I hit 93 a couple weeks ago. Put up a fan and now my tank never reaches 80. It's up to you though. I also don't have the extra cash laying around for a couple hundred dollar chiller and the electric bill that comes from having a second refrigerator in my apartment, lol.
It is easy to get excited when you lose animals and want to spend money to fix the problem. Thats why many of us have tons of chemicals laying in our closests that LFS told us to buy before we new better. Just trying to help, there are a lot of people getting out of the hobby currently because it is too expensive.
