During the day, my the temperature in my tank is usually from about 82-86 degrees farenheit, and i want it lower, around 78-80 degrees. I've tried putting in a few ice cubs in the tank and lifting up the canopy of the tank and having a fan blow on the water, but neither of those things have really helped. I live in Colorado and it gets pretty hot during the summer, so any advice on how to cool down my aquarium would be appreciated.
