A relatively cheap way to keep your aquarium cool
 

It can be surprising how effective a fan can be at cooling your water temperature, especially when positioned between your water surface and light source.

If you don't think you need a chiller, but would like to lower your temps a few degrees, this might be your economical and aesthetically pleasing solution.

I have the 4-fan and I would replace it in a heartbeat if it broke on me. Even on the hottest days the thing keep my reef a perfect 79.

Thanks for chiming in, Brett.

They do have one weakness, though. The clamps won't fit on all aquarium frames. I'll take a measurement at the shop tomorrow.

What's the noise level like?

Fan
 

I paid $10 for an 6" fan.... it does not have fancy clips but sits nicely on my filter.... blows over surface and works like a charm.

In My apartment the tank used to hit 86C in summer but... now always under 80C.

They certainly aren't silent but they also aren't running all the time. Mine run for about 5 minutes every hour I'd guess? Haven't exactly paid too much attention since the noise isn't a huge deal to me. Having two kids may play a part in that!

Fan
 

I put my fan on the same timer as my lights so it is only on when my lights are on.... as in when most heat is generated.

A nice inexpensive dual stage controller and one of these fans would be a dream for me, and solve my temp problems for sure.

i have a 6" clip on worth $8 from wally world over my sump and 4 computer fans in my canopy... cools to the point my heater runs on hot days... i have seen these azoo fans in town but were far above what your charging.... i didnt like the way they are mounted right on the tank...

Thats a smoking price. They are raping you down here. The only store that sells them is chargin 2x that amount.

The tank mounts are 1/2" wide exactly.

I got one of these from Spencer and it has dropped my tank temp from ~85 to 78-79 with the warmer weather we've had here lately.

I have the 2 fan unit on my 50 gallon.

any chance on good shipping???? i would like one 4 fan for my new 120 build

Hi Steve,

Our website is set up to give discounted shipping rates. Try starting the checkout process, and if you're not satisfied with the shipping rates shoot me a PM. We'll work something out. And free shipping over $200 of course.

these are good fans for sure, it would do a job if your tank in basement. I have four of these and my tank is on main floor, could not keep up on hot days so i have to get chiller. Before i got it run like 24 hours and no problem but the dc adapter will get hot

are they continuous or can you set them to turn on when it hits a certain temperature??

on/off with a switch. i have mine plugged into a ranco controller.
