Whoa its summer!!

On my system I run LEDs so I never considered buying a chiller and rev has told me all I need is a fan to chill my tank a degree or two. However, they all seem to have mixed reviews about their performance. Which fans are you using to keep your water cool and why??

I have I 125 gal dt and a 30 gal sump. I use a $12 clip on fan from walmart, because it was cheap and I don't mind replacing it every 6-8months when it gets nasty. It drops my tank by about 3-4 degrees.

I use 2 clip on fans, one pointed at the sump and one in the hood.

Hi Ajreefs,

I also use a small clip on fan that I clipped behind my tank that blows across the surface to help blow heat from my lights away and increase evaporation. I have it hooked up to my aquarium controller to turn on when the temperature goes over 80 degrees. It easily cools it 2-3 degrees.

A clip on fan would be a good choice, but if you have a canopy or limited space over your tank, you can also use small computer fans (usually 3" or 4").

I use the dual one but i found it used so i saved a few bucks. It works great. During winter it's off and as summer approaches you just increase the hours it is on.
