So the other day i got everything i will be needing to construct a frag tank addon to my 90 gallon. Included in that is a 36" Sundial T5HO light fixture. There are 3 switches on the back 1 white, 1 actintic, 1 LED. When i hit the LED one nothing happens? At first i thought it was defective but then read something about them only activating at night or when your timers arent running. Does anyone have this fixture that can help me out? if not i may need to return it soon!
