I am very sorry if this has been answered a thousands times, I am a new pool owner just bought a 30 foot round above ground pool from the previous owners of the my house and it was abused, it hadn't been cleaned in like a year, so after getting everything going and adding shock the past couple of days the pool has went from black to green now to a cloudy blue and I cant get it clear enough to see what the hell I am vacuuming please any help would be oh so greatly appreciated.I have added about 16 gallons of shock over the past 3 days I believe and have had great results so far but it seems I am stuck with this cloudy blue, the lady at the pool shop says to keep adding shock but I need another suggestion so I can get this thing cleaned and sparkling.thank you
