Finally got my TF-100 test kit. Water looks crystal clear and appears great BUT I am so confused!!! Per tests - FC 8, CC 1, TC 9, TA 140, CYA 50, CH 125, pH 7.35. I am confused because the test for chlorine and pH in the blue kit gave me a chlorine reading of 5, but the Chlorine Drop Test gave me the numbers above. What chlorine am I needing to look at and why so many different readings. I read the ABC's of pool chem but I am still confused. Can somebody help me understand what to look at or what needs attention? All these different chlorine readings have me in a tizzy!
