why do some folks have their fuge lighting on the opposite schedule of the DT?

When the DT goes dark, all of the photosynthetic animals which were actually producing O2 all day, begin to consume o2. This will cause a drop in available oxygen and a rise in Co2 concentration, affecting your Ph. By having a Macro algae being lit on an opposite cycle, you have something in the system that continues to produce oxygen as a byproduct of photosynthesis and therefore stabalizing the tank, to some degree, in terms of Ph.

That and its also cool.

I run mine 24/7 as I was told that was the best way to keep Caulerpa from going sexual. Any problems with that?
Thanks

I heard to do the same with caulerpa, I dont use it for that reason. From what I understand, if not worried about a macro going sexual, that a rest time (lights off) is the ideal way to run it, same way that a coral can get too much light and stunt its growth a macro can get too much light and not grow as quickly therefore not export as much nutrients.
