My Algae scrubber runs from ~ 1 hours before my main lights turn off at night to well into the next morning for total 16 hour photo-period. I could actually run a lower photo-period if i wanted at my nutrients are super low. Only reason I haven't adjusted it yet is I try not to make too many changes to the tank at one time and I just added T5's last month.
So maybe this is my main issue???
