Macroalgae scrubber (refugium) photoperiods

[Canadian Man]

Well the post on reefs.org brings up alot of reasons to argue both sollutions.
Tony, my main reason for going with a reverse lighting period is to keep my ph somewhat level, that's it.
I dont really have alot to add to your question but IMO a 12/12 photo period is most realistic.
Oh and hey dont you all ready pay too much for electricity? ;)
