Tank Temperature Question
This is the first time I've had a Salt tank, I've set the temperature to 75 degrees, but for some unknown reason the temp in my tank remains at 81.4 degrees. I have a thermometer in the tank, and I also have the digital thermometer that gives the temperature in the tank and in the house, my house temperature stays between 76 - 78 degrees.
My tank is 125 gallons, 2 power heads, 2 cascade 1500 canisters, a back pac II protein skimmer that has not been used until the cycling period is over. I leave the light on in my tank for 8 hours each day.
My question is: With my tank temperature being 81.4 degrees, is this bad for my fish ? My tank was setup on 02/27/04, I'm still in the cycling period, I have 7 damsels in the tank at this time. I was told that my tank will be in the cycling period for 6 weeks, I'm almost at the end of the 6 week period, I've checked the levels in my tank and everything is fine.
I've been told that I may need to purchase a chiller to help stabilize the temp in my tank, to help keep it between 74 - 76 degrees. Do you feel that I need to purchase a chiller ? Any advice that you can give will be greatly appreciated, thanks in advance for your help with this issue.
