since we only have 3 or 5 days a year at 95 or above, no need for a chiller. Just remove your lids and replace them with eggcrate if possible and put either the clip on fans or the small fans and put the blowing across the tank. I actually open my stand and use a large box fan blowing into my sump to cool it. Ghetto YES, works YES, much cheaper than a chiller i would only need to run 5 days a year YES. all in all, if you have less than one month of high temps figure out something cheap and easy. more than one month get a chiller
