We have been dealing with green water that is murky as the water gets deeper (seen on white walk in pool ladder) for about four weeks, upon returning from a week long vacation. Three weeks ago we shocked it with four bags of shock and it turned to blue again, but was still slightly cloudy.
We are now back to full on green water. According to Leslie Pool we had these values: FC 5, TAC 5, CH 200, CYA 90, TA 90, pH 7.4, Copper 0, Iron ).
We have been using a robotic automatic pool vaccum that is electric (not running off pool suction) that has been picking up minimal leaves. The pool pump has been running continuously for 36 hours.
Added chlorine free shock yesterday and today and are still left green water. The amount added over the two days combined was enough for 16,000 gallons. Did not have this problem at all last year.
Any suggestions you could be provide would be appreciated!
