I have read all the Pool School articles and tried my best to understand how to test for FC only, but I am having difficulty.
I use my TF100 kit with the blue box inside. It has the 2 chambers for Ch and ph. I follow the directions and get an Orange color in my Ch.
-Is this measuring FC or CC?
I have turned my pump back to 9 hrs/day (days ago) and my SWG back to 20% (last night)
I did the "drop test" yesterday I think correctly and the FC number I came up with was like 14.
-I understand that I will need to test again tonight to see any results from the SWG drop to 20% but I am not sure if I am testing the right thing.
My CYA is 75 on the money for an SWG.
ph is 7.4
TA is 90
Thanks for any help.
#2 Am I reading this right and just need to keep dialing in or am I a tool and cannot read the test correctly.
