If your overall light intensity + white levels are not changed I expect some normal regrowth of GHA to easily manage in 5 minute dental runs. it's not like light changing prevents algae from growing, where corals grow algae grow too, but it's a notable help for sure to begin the suppression assistance and it will not hurt your corals whatsoever to bump down the power a bit, or raise up the light/some type of tangible change to intensity and white levels lowered a bit. sustain for two months, re evaluate light levels then. everything we do in guidance now is a 2 months out evaluation, it's slow to track but this is a solid base you've now commanded. I strongly recommend add no new clean up crew, add no form of phosphate and nitrate test + response, all simple manual controls because they work so well and won't be hard in that small/now clean tank until we get lucky or some preventative master shows up to save all your future reef dental visits 
when that master shows up they better have one heck of a gha-fixed-in-ten-nanos work thread.
