When I turn off my pump the skimmer lid blows off with water coming out of it. My water has remained cloudy for three weeks and I cannot get it cleared up. Does the one problem have to do with the other. I have a 24,000 gallon in ground pool with a hayward S244T sand filter with a vinyl liner. I bought the sand filter in 2011 and when they installed it the hooked it up backwards. I had trouble with my water being cloudy all last year and could not get it cleared up. Same problem this year. I replaced the sand and checked the laterals. Everything was fine. I do not have a relief valve. I have put a quart of algaecide and 10 bags of super pool shock with 4 gallons of liquid shock. Also, 1/2 bottle of super fall out and my water is still greenish blue and cloudy. Can you help me with either problem. I have not tried to recirculate to see if the skimmer lid still blows off. Any help would be great!
