I need help! My family was away for 3 days and we left to cover on because there was supposed to be a monsoon. We took the water to get tested at Leslie's and they told us based off what they found we needed dry acid, 2 bags of shock and phosfree. We added the acid waited 4 hours then added the 2 bags of shock. By the morning the water started turning green. We added the phosfree on Thursday and the water is still green. Please help this is my first pool
