cooling fan for 422

[sawzai]

Is it possible for cooling fan to reduce temperature of 422 by 2degree ? If so, which cooling fan?

[BFG]

A fan ability to cool is dependent on the ambient temperature of the room.

[sawzai]

My room temperature 30 degree unless rainy days.
That means able to bring it down to 28??

It is very very hard to cool a tank size like 422, it would be better if you use a chiller

[sawzai]

Its very hard but can be done right? Not interested in chiller though

[seudzar]

I am not sure. But if you want to try, I would recommend you using those 120mm X 120mm AC fans instead of the normal DC fan we used for smaller tank. You can also use those clip-on fan that can be purchased from NTUC.

Or, you might want to look for those air curtain type fan,, the one usually found when you enter an air conditioned shop.

yes,it can be done but the evaporation rate is faster.

thankss i dont mind the evaporation though

[tawauboy]

you can use any floor standing fan that you have a home; for a rough gauge of what you can achieve.
adjust the fan so that air is blow across the water surface to assist in evaporation rate.

right now, you may not mind the evaporation. after a few round of regular water top up, you are likely to change your mind.

try to use DC fans if you plan to place them near or on top of your aquarium. water and electricity does not mix.

my water drops 2-3% daily at least, on my 3 footer... fan chilled.

422 evaporated water you top up.... imagine if you manually top up with pail... MY GOD....
unless you have auto top up system, you will soon feel the dread of topping up water...

[sawzai]

Yup i can imagine the troublesome work to top it up in my 422 but still would like to give it a go , who knows i may get fed up and go with a chiller in the end
What fan did you use for your 3 footer felix?
