Just got it tonight. It a bit intimidating. Took readings for chlorine ph and cya.

Test 1 .2 ppm
Fc 19.4
Cc 1.6

Test 2 .5 ppm
Fc 21
Cc 1

Do these numbers indicate I am doing the test correctly. Also the ph looked to be 7.2/7.4 but when I left the solution on for a couple of minutes it seemed to be much higher. How long does it need?

Any insight would be appreciated.
