Temp Up 2 or 3 Degrees w/ Lighting
I have a 150 gallon tank w/ 400 watts of light (5 x 80), which I run 8 hours a day (3 on, 7 off, and 5 on). The tank temperature will go from 79 to 82 or 83 with the lights on.
Question 1 - Will this change in temp hurt the fish (red line torpedoes, rummies, and cardinals)?
Question 2 - Is there anything I can do about the temp change?
