How To Keep Water Cool

    Is there a way I could keep aquarium water cool without getting a chiller? I have an aquarium fan which does a pretty good job but I still need the water to be a couple of degrees cooler, how can I do that?

    Put frozen water bottles in the tank and do more water changes with cooler water.

    I know a lot of people freeze water bottles and float them in the tank to get the temp they are looking for.
