I've been running Radiums with T5s for over a decade, not having $$ for LEDs. Heating the tank and the house, then using the chiller to cool the tank while really heating the house and running a/c and paying serious $$$$ on electricity. FINALLY buying new Radion XR15s today and expecting them to pay for themselves in less than a year!

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.

That’s because you’re all nuts, haha. I used to live there awhile back.

Had a heater on my 32g biocube for the first 2 years because you’re “supposed” to have a heater. Noticed the temp on the thermometer was a little higher than normal even after turning down the heater significantly. Decided to take it out altogether and the temp was still reading at about 82. Bought a new thermometer thinking that was the problem but the new one is also holding at 82. Just going to leave it as is and stop messing with it.

Frozen bottles of RO water in the sump!
I used to live in Riverside, Cali (Desert, many days above 105F)

Doing my first summer in KY, and my tank is in the (cooler) basement.

Cheap little Walmart clipon fan does the trick for my 55 gal. Surprising how well it works for its size and I get 2-3 degrees drop in temp.

How much did tha
I am using a 1 HP Carrier outdoor Aircon compressor which connects to a titanium coil in the sump. Compressor is controlled by APEX Which switches on and off between 25.6 and 26.2 degrees Celsius. (78-79 degrees F)

How much did that setup run? Where did you get the coil?

Perth Western Australia gets hot in summer but humidity very low so I made this. I use a temp probe to power them on when water goes 27°C or above then cuts off when it's back down to 26°C. It's extremely effective. All plastic construction including screws and nuts. Cost to build around $50, not including 12V 1A power supply and probe/power unit. Those combined were another $50. A lot cheaper than a chiller and uses much less power.

For those of you using clip on fans over your sump.
If it has room to fall in, put a small tether on it. Use chain, rope or even a tie strap because accidents do happen. Be safe out their

Since 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:

Do you use a fan or chiller on your reef tank to keep the temperatures from spiking too high?


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

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 well

tank is in the basement. basement temp never gets above 76.
my problem is humidity. during the summer if I don't run two dehumidifiers, all the pipes start to sweat. and there's a lot of pipes as I have a well, boiler & water softener in the fish room.

My House A/C keeps my temperature controlled in the summer months as long as I don’t let the house get too hot my Temp stays stable.

Run your lights at night and make keeping tank cooler easier. Many homes have AC that struggles during the day.

I run a chiller. I live in Japan and the summers get hot (Sometimes 100*+) and extremely humid.
