Reply With QuoteI'm using a 2nd hand ANS cooling fan for my 1.5ft tank, pretty strong wind but the evaporation rate is quite high too.
Currently looking for a good quality aquarium fan for my nano 5.5G tank.I have no interest in chillers or ice packs as they take up precious tank space, but I am also not too familiar with aquarium fan brands/type. Please recommend me a good one from your experiences.

Im using the dazs brand for my 5g tank. Does the work pretty ok and managed to bring down by 1 to 1.5 degrees celsius. I have only used this brand so far because the rest looks too big when compared to tank size.
You could also look at the Aqua World cooling fan, its a low-profile hang-on design similar to the Dymax ones. They have a version which comes with adjustable fan speed adapter too, so you can tune and reduce the fan speed to make it quieter (in case you are bothered by the fan noise at max speed).
Looks like this:

Thanks for all the replies guys!
@Wing Thanks for the info, but it seems that I forgot to mention that my tank is a 1×1 feet, so that ANS fan'll be too bulky (and unsightly) for my tank. Also you didn't mention the cooling rate for your tank too.
@destress That fan looks and seems pretty nice, but the color is rather bright. I'll consider it and thank you.
@Urban Looks very sleek and compact, love the colour too. The added options are a rather nice touch though I have yet to check out the price...
Thanks to everyone who helped me. I'll try to find either the Dazs or AquaWorld brand in lfs.
I've used Dymax W8 before, it got nosier after a few months due to dust trapped inside and eventually it stopped. After that I've changed to ANS fan and found out AC fans the CFM is higher than DC fans, cool my tank much better, but higher evaporation rate. Of course the trade-off is bulky and ugly. Hope to change to a chiller one day.
Yeah, i agree on the enclosed ducted fan designs... they do trap dust over time and should be opened up and cleaned every few months to maintain optimal performance (kinda like cleaning your PC CPU fans periodically).
Those open-faced fans don't look as sleek but they don't trap as much dust, and are easier to clean and maintain too.
Do you think u really need a fan for ur 1ft x 1ft tank? I have a tank in A4 size (210×297) too. The water coming out from my filter is good enough to give surface agitation to cool down the tank by 1 to 1.5 deg. The water level of my tank drops by few mm per day and I need to do water top up once every few days.

Theoretically, cooling rate is evaporation rate. When water evaporates, the gaseous state H2O will bring along the heat energy from the water surface, thus the more water evaporates the cooler it will be. Water surface agitation also contributes to the water evaporation rate.
@WingCher, this is what I mean also. Water agitation alone is good enough to evaporate the water in a small nano tank.

Everyone's tank is different, even if the size is the same. I have floating plants so my water movements is close to nil, therefore the need of a cooling fan. Not to mention the temperature's at a constant 28ēc and may rise to 30ēc on a bad day- which I have plenty of in such hazy weather. :/Originally Posted by Kingelliot
My cherry shrimps tank also has floating plants which I will clear some out weekly, as I found that they are trapping heat in my tank if they were to cover the entire surface. Hence I came to understand the physics behind it - the floating plants are hindering the evaporation and thus unable to lower the temperature for my non-chiller tank. Even with a fan, it will be blowing on my plants surface instead of the tank water, therefore deemed ineffective in cooling down my tank.
That's actually a good point, but what else can I do then? The LFS recommended me to use ice pack/bottles, which is what I am currently doing. However the iced bottle takes up alot of space and disrupts the plants frequently.
Buy a chiller... =p

Like stated in the first post, chillers are too bulky and will take up tank space, not to mention that few chillers are suitable for such a small 5.5G tank. The price is also another thing as I can't afford something way over $100 at one go.
Ice packs or bottles? Is it just release the ice bottle into the tank? Wouldn't it spike up the temp too fast?
Read the previous posts. Also, placing the iced pack/bottle into the tank won't cause the temperature to spike up. Online and many others say and prove that this is one of the cheapest ways to keep your tank cool. Only if you dump in ice water straight into your tank, then will there be a spike in temperature.
