Is this good algae? ID PLEASE

Lower nutrients:

~ Check your feeding (and rinse frozen food before feeding)
~ Good skimming
~ Regular water changes
~ Carbon, GFO, etc
~ Carbon source dosing (vodka, Zeovit, Fauna Marin, etc)
~ Check water flow (maybe your rockscape needs improvement, or more powerheads)
~ Check bioload
~ Be sure liverock can handle the livestock load

You need to cook the rocks for a lot longer than a week or two to kill the hair algae. Probably more like 4-6 weeks, probably longer if you want to leech the phosphate and nitrate out too.
