Can you swim in pool hat has a normal chlorine level but the free chlorine level is high?

There is 3 measurements of chlorine in a pool or spa. Total chlorine, combined chlorine, and free available chlorine. Free available chlorine is the good chlorine that is active in the pool killings germs and algae. Combined chlorine is chlorine is basically chlorine that was once active but has killed germs or bacteria and is now inactive in the pool. Total chlorine is free available and combined chlorine added together. If your combined chlorine is higher than free available chlorine then the water needs to be shocked to eliminate the combined chlorine. But be careful here. If you don't reach what's called break point you will only add to the combined chlorine. There are products on the market which will only remove combined chlorine without effecting your free available chlorine if you are unsure about reaching breakpoint. Hope this helps.
