I have a 33' round pool. I did not cover it last year. I think I have most of the leaves out of it, can not see the bottom. Like many I went to pool store and they sold me some algae killer, 4 gallons liquid chlorine and 5 bags of shock, told me to dump all of it at once. I also bought new sand, because i think i have a broken latteral and was gonna fix that.
My question is should I change the sand before I add the chemicals?
When I add the chemicals should I use filter or baypass to pool until water starts clearing?
