Hi
I just wanted to know if this is normal.
On 5-12, my FC was 14 and CC was 0 (after several days at or above SLAM levels). I did the overnight test and my FC only went down by 1 (sunny days) and the CC stayed at 0. I assume I was in the clear. Now 4 days later and after probably every bit of 1.5+ inches of hard rain, I tested my FC. It is 5 (tested 2X to be sure) and the CC was .5
Is it expected for the FC to drop that much in 4 days? I am thinking so b/c of getting so much rain water (my pool is almost to the top).
(This is the first week of having my TF100 test kit. I have tested the FC and CC and CYA multiple times--mostly to get used to the process and verify I am doing things correctly. I plan on doing all the weekly testing on Sundays and the small kit of FC and PH daily to verify FC at +/- 5ppm.)

. I saw all of my levels drop quite dramatically, after doing some calculations, I essentially had around 20% of my water replaced. Hopefully that won't happen again for a while!
