I recently upgraded my bulbs on my 20g high from 2x 13 watt to 2x 23 watt CFL bulbs. Before the upgrade, my temperature stayed in the upper 70's. However, I just noticed that with the bigger bulbs, the water temperature is getting a bit too high for my comfort. What should I do in order to keep away the heat, but keep my med. light plants happy?
