Taking my Skimmer offline

[Frogger]

I just had a good question about O2 levels in the tank and taking my skimmer off line. That s why I am running an ATS on a reverse lighting cycle so that photosynthesis will always be occurring thus using CO2 and producing O2 during the daylight phase of photosynthesis.

I could always run an airstone if I was concerned or turn the skimmer way down, if that was an option (my skimmer still works way to hard even at the lowest air setting).
