Your in luck I work in a water lab, First adjust the PH to 7.2 Then add about a pound of stablizer this will cause the water to hold the hypoclorite longer if you already put in algacide & clairifer thats ok once the PH is 7.2 and Stablizer has been in for about 3 to 4 hours Shock again and it will take about 2 or 3 days to clear up Good luck. YOU MUST AT ALL TIMES KEEP THE WATER BALANCED.
