thanks for the tip, will follow advice. can people swim (using old bathing suits, of course) if fc is in the 25 ppm range?
gonna be pretty hot in the northeast in the next few days.

For most people, swimming in chlorine at that level is not a problem but do wear the old suits of course.

Thanks for doing the signature line!
