| Before you invest in a chiller and all the electrical costs to run one.... buy some fans (just like wes said) and you might be amazed at the temp drop. Fans cause evaporation and evaporation causes cooling. Your tank may easily drop 4 degrees.
What kind of lights do you have? What kind of ventilation for the lights? Are there glass lids on the tank?
