can someone link (no luck googling) or explain the relation between free chlorine and cyanuric acid.
FC is the sanitizer.
for sake of easy comparison. let give FC has a sanitizing power of 100.
with CYA at zero. FC will obviously have its full sanitizing power of 100.
with CYA at 30ppm. FC will bond to the CYA (hence the stabilizing).
questions. what happens to FC's sanitizing power?
questions. why is a higher FC ppm needed for shock?
