I have a really bad problem. I have been trying to clear up a cloudy pool. I was told to shock it with 3 gallons of bleach and then run pump for 24 hours I did that and nothing worked. I have the pool on a timer for 6 hours a day while we were away on vacation for 5 days. We come home and my pool is BLACK! The bottom is black like mud. I dont know what to do. I have tested the water and nothing is right....about to give up, drain it and start all over.....any one have any suggestions before I go to plan b?
