I was wondering what the safe swimming levels are for free chlorine. I was looking at the HTH website regarding a question I had for the stabilizer and I read a comment that swimming above 4 ppm for free coloring posed a risk to your body.
I've been through all the pool school articles a couple of times and I can't call seeing anything that specified book the safe ranges were for any of the items that we balance. For example I was shooting to have my pool, which is a saltwater pool, at a CYA reading of about 60 or 70. That puts my maximum free Chlorine at 4 to 5. Both above the limit that comment referred to.
Any insights on this when running a trouble-free pool would be much appreciated. Thanks!
