I just moved my corals (softies and sps) to a new 215g... I will be adding a chiller this Sunday... However, due to temperature issues I can only run the lights for 3 hours before the water goes from 80 to 83... not running a heater, the return pump keeps the tank at 80, with the house set to 71 during the day and 67 at night... Is this enough light until I get the chiller hooked up?
