The ONLY way you can get rid of it without fighting it for months and months is if you shock really high for 3-4 days, by really high, I mean getting your free chlorine up to 20 - 25 ppm and keeping it there, while running your vac to suspend the algae and allow the chlorine to completely surround it and kill it off.
Thank you for your post, but as I stated, I shocked the pool and ran my barracuda. This was well over a week ago. The pool cleared up and has been crystal clear since. I have not had to shock it again, just maintain the balance. The pool looks beautiful.
