Niko, I've got blue T5's alongside my MH's. Would a moonlight produce a different type of light? Was looking at the Aqua Medic moonlight which is about £60.
I used to have my lights on 12 hours and off 12 hours, but then i got red slime algae and cut them back to 9 hours...turn on 12am and turn off 9pm via timer. Everything seems fine with that so far.
Hope this helps,
