I am a little confused over Total Chlorine, Combined Chlorine and Free Chlorine
The HTH 3 way test kit to my knowledge, measures Total Chlorine
My test strips measure only Free Chlorine
I currently have no way of measuring Combined Chlorine.
It is my understanding that Combined Chlorine = Total Chlorine – Free Chlorine
So if I have free Chlorine at 2ppm
and Total Chlorine at 5ppm
I have combined chlorine of 3ppm and I need to shock the pool ? Even though it looks great, sparkling and clear ?
No I dont have a Taylor test kit, im In Ontario Canada and they are next to impossible to obtain.
