Timely question, I’m installing a chiller right now.

That’s because you’re all nuts, haha. I used to live there awhile back.We live in the Phoenix suburbs and let the AC temp run at 78 during the day. The tank can spike up to 83 with no fans. (I tested it back before I had corals in it) I originally had bought the GHL 4 fan unit, controller and have it hooked to my Profilux 4. I would still see temps hitting 80. I try to keep my system at 78. I bought the GHL because it looked pretty... It's good for a 2-3 degree decrease
So I bought a cheap Vornado fan at Home Depot and it brings the temps down to the 78 mark. Presently I have to manually turn on the Vornado fan and I do it when I see temps rising above 79. Eventually I'll quit being lazy and connect it to my controller. With the Vornado running the Tank will drop to a temp where the GHL shuts off and heaters need to kick on to keep the 78 temp.
If I had to do it all over again, I wouldn't buy the GHL fan set up. The Vornado fan does a great job by it's self.
I use a clip on fan but I also have those things u keep in ice chest. Ones I have can fit between my baffles and I have enuff to rotate them. Works wellSince it's heating up outside I thought today would be a good day to remind everyone that it's not expensive to keep your water temperatures down!
Do you use a fan or chiller on your reef tank to keep the temperatures from spiking too high?
Depending on your equipment, tank placement and the area you live sometimes it's near impossible to keep temps down without some help! It's really easy and cheap as you just need to get the air flow moving over the surface of the water. A fan blowing across the top of the display water or sump will work. Even a frag tank as long as it's plumbed into the main system.
Please note that you will also have more evaporation and will need to top your tank off with fresh water more often as this heat exchange takes place!
So here are some easy and cheap solutions!

So the question of the day is this:

@Gablami chooses to cool this reef via GHL aquarium fans.
