Hello all. I am new to the bbc method and had a few questions. I bought a taylor k2006 kit. my ph 7.4, FC-9, ta-90, and cya is reading 90. I just opened my pool last week. The only chemical I added after opening is two bags of dichlor shock. I was confused on how to test the cya. I am supposed to keep adding the cloudy solution until the dot completely disappears, or just barely disappears? This test is tricky for me because I sometimes can not see the dot and then it will appear again in seconds. I do not know why I would have such a high cya level if I have not added any conditioner. Could my cya level be falsely reading because I just shocked my pool with dichlor? I would not expect shocking 1 time would bring my cya that high. I filled about 3/4 of my pool with fresh water this year. Could I be getting a false reading because my cya is zero? any tips on reading the cya test with the taylor kit? Thanks Jeremy
