Living in Arizona means dealing with high temps during the summer. We keep our house AC
set at 78. I have been watching my tank temperature for the past 2 weeks and have noticed the following.
In the morning when I first turn the lights on, the 70 gallon tank is at a nice 80 degrees. By the end of the day when I turn the lights off the tank temp is just under 82.
The tank is lit by 2 flourescent lights. I was thinking of adding more light to help the plants grow better, but that would also cause the temp to increase.
So I want to know, do you cool your tanks? If you do, what method do you use. I could try and increase the evaporation, but with Chandler water, that would mean a lot of hard water deposits. Are chillers worth the expense?
I just can't justify keeping the house at 74-75 just for the fish.
Let me know what you think.
