Hi All. Great info found on this site!
I realize this is the time of year people are opening their pools, but I have questions regarding closing the pool. I have own a pool for the past 8 years and every year I have a green swamp when I open. Can anyone tell me what I would need to add at closing to prevent this SLAM every year? I have a 18X36 kidney shaped concrete, vinyl lined pool. 4' in shallow end and 8' deep end. Sand filter.
Any suggestions would be welcome. Thanks.
