Using bad test strips allowed CYA to go to about 160 ppm according to my new Taylor K-2006 test kit. I super chlorinated the 15K pool with 10% NaOCl and a week later the FC is still high at 25 ppm. This was done to get rid of a bad algae problem. The pH is a bit under 7.0 and the base demand test calls for about 2.5 lbs. of soda ash. My question is, if all other parameters are OK, is a FC level of about 16 ppm going to sanitize my water and still not irritate the swimmers? Of course I am not going to add stabilizer and plan to drain about half of the water when summer is over.
CYA Too High

Confining myself strictly to your question, yes.
My first summer I was stuck with CYA in the 220-240 range. Hard to be more precise when you;'re diluting things 1:3 and 1:4. I kept the FC up in the 20s and swam around -- without goggles, even -- with no problem. Swimsuits didn't bleach out or anything.
