you did not tell us whether you are having an open top or canopy.

for open top, temp will go down.

canopy will trap the warm air inside thus temp will not reduce.

I have a 2 fan type for my 2 ft set.

I put it near my powerhead.

It manage to drop my temperature by 2 degree.

Btw, there is not canopy for my tank.

you may wish to try this..... get 2 fans... one to cool the lights and the other to cool the water... put it about 1" above the water surface and blow it 24/7.

i have only 1 fan blowing the water surface and it has helped to cool my 2ft tank about 2-3deg.....

best of luck

I am using a ocean free brand to cool my 2ft by 2ft...can bring down by about 2 deg, but there seem to be a high evaporation rate

The fan blowing at the water must tilt to an angle to optimize the effect.

Works for me. Now doesn't reach 29 deg anymore

have used for 3yrs + & very effective. set the fan to blow directly on the water surface (if u can) or max. 45 degree. fan sud be above water surface not more than 6 inches. it sud cool down at least 1-1.5 deg. but be ware as u need to top up at least 2-4 ltr of fresh water a day. downside is u may have a lot of nusiance algae due to phos & NO3 in the tap water.

all the abv is based on my past experience. may not be appliable to all.

i also using a cooling fan.... on it 24/7... the temp of my water is about.. 26 - 27 degrees for my 2 ft tank... but sometimes if i on my aircon... the temp can go down to 24- 25 degrees.... heheh ... coz the tank is in my room....

nice temp for the corals.. when it is around 25 degrees... hehe

How to diy your fan when u buy it from sim lim square ?

[jc85]

A gd guide here.

[junyong84]

mine is open top..

my dad help me rearrange the fan again...yup ...manage to bring the water down to 25.5 - 26. without lights on

26-27 with lights on...

[guppy]

I got a 4 fan in a row type, after one month, more and more noisy, slowly

one by one die off until left with one working. Give up , take it out and bought

one diy fan from Sim Lim $20 (0.12A)without holder, drill hold here and there to secure the fan to the tank. Saw LFS having one with holder but selling $32 to $40.

Finally saw the same fan at N-ture (balestier) selling at $28 (0.12A). Bought it!

So...why take the trouble to diy and mess up the whole place.

Hi UFO,

So do u have any solution to prevent these algae growth? If u do please share with me. I do experience wat u have mentioned. Thanks

hi experts, can the DIY fan place at the sump tank insead of the main tank, would it help?

You won't know until you have tried. Everyone has different systems..

[alanseah]

for me, for years I never use any fan or anything to cool my tank. It some how have been mantain at 27 to 28. And I'm happy about it

[reef2]

yr tank must be in a air-con room... and also yr lights should be weak too. + any heat from powerheads, etc.... else maintaining at 27-28 is impossible.

[Aspire]

Mine is a canopy tank. Will cooling fan help to reduce temp? shd I blow it on the water surface of let it stuck out the hot air??

[alanseah]

my light I'm using 4 light in 10K kelvin. I dont use powerhead. i use 2 water plumb at the water flow rate of 2600.

it's a 4 feet tank with 6-7 inch sandbed.

Yup it's in the air-con but only at night then the air con is on. Day time I just leave it like that.

it's up to you to believe it or not.

[junyong84]

i got this feeling that...the higher ur bioload.. the higher would be the temp..

coz living things trap heat and gif out heat...

charlie,

that's is 1 of the biggest problem i'm facing (if not most reefers). there are a few well know methods/solutions:

DSB

RowaPhos

Macro Algae in refugium

I'm now trying all the above & hope to prove it right.

[Sinn]

or u could buy a ro unit...
