Blood in water - adjust FC??

[crek31]

Had a swimmer yesterday who had several fresh strawberries from a morning bike crash. No dipping blood, but large raw areas that were bright red where the skin had been rubbed away by road rash. I let him swim with the kids, and bumped up FC to about 7 (cya is 40) afterwards. Is that sufficient, or should I bump it up higher, longer, or go to full shock? Thanks!

Germs that could be in blood are not generally a problem. Maintaining adequate chlorine levels and proper filtration are usually sufficient. You could bump up the chlorine to about 20 to 25 % of the CYA and increase the filtration run time for a day or so, but that's just being extra cautious.

Thank you, James.
