I think you may be right. I do not have a good kit yet but I've added enough bleach to the water (per this website) that I believe my water is staying at shock level between 12 and 15. With the FC level staying so high the water is even more cloudy. But I also have a sand like dust on the bottom of the pool and when swept it throws a big dirty cloud but I have not wasted in several days therefore it might just be dirty cause we live in GA and everything is blooming here. Does it matter if my FC levels are high when I add the metal sequestrant? Also my steps are an orange color does that mean a certain type of metal? And if I do add this how much should I use? Thank you so much for all your help :-)
