Default Macroalgae scrubber (refugium) photoperiods

If and when I get my refugium hooked up to my main tank, I currently plan on running the lights on a 7x24 basis.

I figure it would be best to have the macroalgae generating oxygen all the time. The critters will get accustom to the 7x24.

The big question to me is - does the macroalgae need some down time in which it needs oxygen to regenerate/grow?
