hi all, it seems to me that my coralife 250 watt 48" inch 10,000k and actnic blue lightings system is keeping my system at 80 (or so ) degrees. i am runnigs only 150 watts of heater in the sump, and they are both set at 76 degrees. i don't want to have the temp fluctuate that much from day to night.in my other tank, a temp problem made all of my fish succeptible to ich and they all died. i do not want to do that again. my tank dimensions are 48"x12"x19" and is a 55 gal. is this too much lighting, as far as temp goes? i have the light on the provided 3" stands. should i raise the light up some more, or get a water cooler, or what? appreciate any help
there is another heater by the skimmer one 100 watt and a 75 watt
