After the bleach...green is pretty much gone...yeah!

Here are day two levels:
Cl = 5.0
Br = 10.0
pH = 7.8
Alk = 210
Hardness = 410
CYA = Same as yesterday

Now our question is, yesterday everyone was saying to get our chlorine level up to 15 ppm but when I look at tester we have it doesn't go up that high. Am I not reading it correctly or do I need a different tester?? The highest on my tester is the reading above
