I had a cheap led light on my 20 gallon tank. The water temp stayed at 76 to 77 degrees. Now that I have a 4 bulb t5 set up, the water temp has gone up to about 78 to 79 degrees. Is that ok ??
I go from about 10 to noon with blues only, then whites come on around noon and they both stay on until about 8 when the whites go off and the blues stay on til about 9 or 10 pm.
