In the summer, my reef tends to hit 81°F or so, while in the colder months it maxes out at 80°F. Years ago, I programmed the Apex to turn on a fan if the tank gets over 79.5°F but there wasn't a fan plugged in. Until recently, that is. I finally got around to making an acrylic bracket and put a 120mm fan over the return section of my sump. This one fan, running in low-mode, has kept the temperature one degree cooler over the past few weeks. I probably should have made it hold two, but one is better than none.

I used some wet-application 3M doublestick tape to hold it on the rim of my sump, because there really was no good way to rest it anywhere.

Here's the past seven days. There's one spike that got a little higher but it was especially hot that day and my house was hotter too. It was an abnormal day, and even the weather app said "Feels like 108°F" and I totally agreed.
