That is correct, my bubble only present after long period of expose to light.

My nirtrates is not detectable.

Does moon light do anything to the reefs or just for looks.

Moonlights are mainly for looks, though if timed properly can give the effect of a lunar period which may induce spawning behaviour by some animals.

well, i set up my timer that at 10Am the sun light will go on until 2 pm, then moon light will go on for 2 hours, then the sun light will turn back on at 4:00 pm until 10 pm. Moon light for another 2 hours then shut off. is that ok.
