Hey Everyone! I have completed my drain and refill to get my CYA down from the initial 144ppm to what I believe is 45ish ppm. The pool refill was done using well water and I noticed a brown stain in the corner where the fill hose was. I'm assuming this is an iron stain as it wouldn't brush off with my pool brush.

Next I found the backwash which is normally green to be brown. You can see it in the photo. Unfortunately we had a TON of rain yesterday afternoon and it flooded the area where I backwash but the brown is from the filter.

Overall, the pool looks good. My last test results are:
FC - 7.5
CC - 0
pH - 7.2
TA - 280 (I'm guessing from the well water)
CH - 310
CYA - 40 (I tested normal and did a diluted to make sure I wasn't crazy)
So, IF the well water has high iron (which I would guess it does), is there anything I should be concerned about? Once again, I appreciate all the guidance!
