Cyanobacteria question

So I have a minor cyanobacteria outbreak and would like to nip it in the bud.

I have cleaned out all media in filtration.
limited lighting and feeding.
ammonia = 0
nitrates = .05-1ppm
nitrites = 0
phosphate = 0
Doing weekly water changes using RO/DI

I realize phosphates and nitrates get trapped in the slime so even though I'm reading 0 when testing i'm going on the assumption there is enough in the water to facilitate the red slime growth.

Its a 75 gallon. About 3 months old. Have LPS, SPS and fish with about 75-80 lbs of live rock.

Question is Should I get a protein skimmer and will that help? Or should I go the red slime remover route (which I would like to avoid.)

A protein skimmer would help by removing stuff from the water column and IMO, highly suggested.

As for the red slim, this is a natural stage for your tank since it is young. Syphon out the red slime and maybe reduce your lighting period and intensity if you can. If you are unable to do that with your lights, raise the lights up to get them further from the water line.

Good luck
