Keeping my tank cool

My tank's water has been hovering around 30 degrees during the day when its hot. This is obviously a little too warm, esp since I want my Java moss to grow

So last weekend I bought a PC fan from computer shop. Its about 8cm x 8cm and runs on 12v. Its pretty quite too. The 220v-12v transformer is on the same timer as my lights. The fan is installed in the hood and blows air over the water's surface and over the lights.

So far the temperature has not gone much about 26 which is a amazing improvement for such a simple setup. I can't comment on the increase in evaporation yet, though I don't particularly care as I do weekly water changes anyway.


Just though I would share

 

Thank you for sharing Dart.

I use a normal room fan that works great!

 

Do you guys keep you heaters running during summer?

 

Mine is on but it is not doing very much....

 

Does your tank get a lot of direct sunlight, Andre?

My tanks drop to around 20?C when they're unheated.

 

Yeah it gets a bit of direct. It also gets plenty of indirect light, enough to keep it pretty warm.

 

Ok. I guess you could always go nuts like the Singapore guys and buy a chiller...

 

Or you can air-condition your room, that way both you and the tank get the benefit
