cyanuric acid

[JohnT]

heres the numbers
copper =o
iron-o
ph= 7.4
cya =132
total hardness=263
total chlorine .9
total free chlorine .7

I did supershock-it as they suggested so the reading now will have a chlorine

And when you shocked it, you added more CYA or calcium. You have to stop using dichlor and trichor if you want to keep the CYA down.
