Now that summer is round the corner.. I see sometimes my water temprature reaching 80.
So what do you guys do to keep your aquarium temprature cool.

I'm serious...I have central AC and keep the temp in the house at 72 degrees all summer long so my heater will have to be adjusted accordingly once the temp is regulated for the summer.

Buy an airconditioner for the room with a thermostat. I'm gonna have to do this for my room if I end up getting hillstream Loaches.

Either central AC or AC for the room in which your fish are. But if your house doesn't have central AC ... it is rather impossible to get it fast, lol. So a room AC is the better option. Or ... there are aquarium chillers (just like there are heaters) only I think they're very expensive. If you can afford one and if you don't have any kind of AC, you could get an aquarium chiller.

Yes, I've heard chillers are very expensive too. But don't worry about 80* unless you have coldwater fish.

Goldfish would be able to survive at that temp but not for a prolonged period of time, perhaps a few days tops

One way to cool tanks is to increase the evaporation rate.
This does lead to having to replace water at a fast rate though.
By running a fan so that the air flow is directed at the tank will cool it.
And a fan is a lot less expensive than a chiller or AC.

The problem with that is you don't want to add water to your tank to top it off as it does nothing to eliminate any possible chemical buildup.....

How about putting in a couple of ice cubes formed out of tank water !!!!

If you are doing your weekly water changes then topping off the tanks when it needs it won't hurt anything.
As Dino said a fan is a lot cheaper than AC and it works.

Water to replace evaporation has nothing to do with the water changed out for maintainance.
It is simple thermodynamics, remove heat from a system,the system will cool.
I used this method for over 10 years while keeping fish in a greenhouse in the summers.

It's really not that complicated. Thermodynamic processes naturally occur within the system itself anyway every day. It's an open system.....The filter provides the energy, the heater creates the desired temperature, which is more often than not warmer than the surrounding temperature creating condensation and evaporation......What we are attempting to do is further artificially control that system.

Since you are keeping fish in a greenhouse, you are creating an artificial environment whereby the heat and humidity levels are increased having an effect on your rate of evaporation. The thermodynamic process further occurs when you extract heat and create moisture in the form of condensation which occurs as a result of evaporation as we said earlier. In a greenhouse you sometimes see that condensation build up on the glass. Yours is a special case, I would think as the average person is not keeping their fish in a greenhouse.

If you position your fans where they will have an effect on the water's surface, then more evaporation will occur. But we are assuming that the average person will be attempting to cool their tank within their home with the tank covered. If they reduce the setting of their heaters (as they should), direct the airflow at the glass itself, thereby cooling the outer boundary of the system effectively reducing the water temperature within, then they really shouldn't see too much of an increase in evaporation. However, if the tank is cooled too much, condensation may form on the outer surface of the glass. But that would have to be an extreme temperature drop.

And actually it does relate directly to the water itself if a person is continually adding water without removing the minerals and disolved waste that build up over a period of time. The misconception would be that as long as they're adding water back into the system at a faster rate than normal, then there would be no reason to do water changes when quite the opposite is true. Which was my original point.
