I'm just bust'd&can't figure out.The past couple year's every time I have people over to swim.Water will get cloudy within the hour of swimming.I've tried increasing clorine&still doesn't work.I check'd water after ther swim today.Now mind'd that I alway's add clorine in the evening's.I decided to check while there were still in water.Test result's.FC 3 CC 0 Alk 70 PH 7.5.CYA 45.I noticed that FC has fell below the min of 4 with my CYA being 45.Like I said I've tried running it higher.But,the problem is I start having a bleach smell.
