Are there any tips for doing the Chlorine test with the Taylor test kit that comes with the TFPTK? I can't distinguish between those shades of yellow beyond the lowest level. Will the difference be more distinct when held against a different color background?
Also, I used the chlorine chart here at TFP to shock the pool but the test kit only goes to 10 for chlorine anyway. Again, any tips? Or am I doing something horribly wrong, as evidenced by my questions?
