changing light schedule

[bri.reffin]

school is starting back up. and my selfishness wants to wake up to my aquarium lights on.
i'm currently running (13 on 11 off with 1hr ramp) and would want (15 on 9 off with 1 1/2hr ramp)
would this be okay? i've completed the 30 day accumulation of 50% just recently and haven't tweaked the % current 15 on 9 off

A PAR reading is the only way to tell for certain.

there are threads and some reading material on photoperiod for corals, consensus opinion was generally not good +12hrs …
No opinion here eitherway as I’m cheap and rarely go over 11hrs anyway
