Kind of diverging from the original question, but help me understand this. Does this hold true if I have insanely high CYA levels? I'm limping along and delaying the refill,but with a CYA of 500, PoolMath says I should shock at nearly 200PPM of FC. So "safe to swim at shock level"???
As to the original question, I believe those levels are fine for swimming and wait about 1/2 hour after adding chemicals -with the pump running- before swimming.
We say it is safe if the FC is greater than the minimum and less than the shock FC level as listed in the FC/CYA Chart. AND you can see the bottom of the pool.
