Cooling Fan

[connorsbala]

Hey
I have an axolotl tank and they need coldwater. But,the temps 22 degrees celcius at the moment so a lil to hot,but they are coping. So,you know in marine tanks they have these fans over their sumps,i might get one for my axie tank...what do you think? Do they work? Would they cool it down more importantly? Im after one like this:

DO you other axie fans use them...if not what do you use to cool it down with? At the moment im using de-chlorinated ice cubes.

You could use what computer watercooling enthusiasts refer to as a "bong cooler" . Fans will really only bring the temp down to ambient or perhaps 1C below if you use a lot of them. To go further you either need a chiller or something crafty like a bong cooler.

Can you elaborate on this "Bong Cooler" I am not a smoker so Have no need for cooling My bong but cooling my smallish tanks in the summer heat (which wiped two of my tanks out a few months back) would be very good. Chillers are still a bit out of my price range.

Ok I see. It seems pretty ironic that the computer guys use a bong to stop their computers smoking. . I will be looking into this further.

Arf!

Amen to that. I used to use one back in the day to keep my computer from smoking. Worked really well but needed cleaning every month since the showerhead eventually gets plugged up. Kept my processor just a few degrees above ambient and the water in the resevior at the bottom of the bong cooler was a few degrees below ambient.

So thinking out loud... Could you have this "Bong" above the tank and a pipe out of the bottom of the "bong" going straight into the tank with a powerhead pumping the water up to the top of the bong? Seems pretty simple but just how to make it look good perched above the tank. What about somehow combining a trickle tower and bong together in the sump (not that I have a sump) with lots of air getting pushed up through the media with the water trickling down.

 

[SkiFletch]

Placing a fan over a tricle tower would give the same effect for sure. See the idea is that when you create those finer droplets of water through a showerhead or trickle tower, you VASTLY increase the surface area of water, and therefore vastly increase the evaporation rate. Evaporation cools the water, and you can figure out the rest.

Do remember that with either a bong cooler or trickle tower, you will hear a water trickling sound. I dunno how annoying that is for you and anybody you may live with but keep that in mind before you jump headfirst into the idea

Yeah, noise I didn't think of yet. I have all year to think about it and play with the idea, since I am in South Australia and the hot weather is over for now. Another way I did think of which I think is similar to an evaporative air con is having a sheet of foam or japanese matting or similar and having the water flowing down through that and a fan on it. That would have less noise as well. I better think about a top up system as well as I would be losing plenty of water with any of these devices.

Amen to that
