This seems to be a new issue, I didn't find anything like it under the search function. I swim at 5:30 am, and do 2000 meters, freestyle and kick sets. I just recently started taking more strokes between breaths, I was doing 2-4, now I'm doing 6-8. I do have asthma, but I've not had problems swimming before, and I don't have any issues while I'm exercising. The onset of symptoms is usually around 5-6 hours AFTER I finish my workout. Anybody out there ever have this happen?

A chlorine level of 10 ppm is desired for a super-chlorination or a shock treatment. 13+ sounds dangerous.
