This is my first year with my inground pool and I'm learning as I go. I received results from the pool store but wanted to get your thoughts on what I should do next. My test results as follows:
FC - 8.1
CC - 8.6
PH - 7.3
TA - 3
CH - 265
CYA - 144
My chlorine is very high and should go down soon. I'm putting 2 3" tabs with a setting of 3 on the chlorinator (as opposed to putting in 3 tabs with a setting of 5). Should I shock the pool to get the CC down?
I have no alkilinity b/c my CYA is very high (I added 30 lbs of alkalinity and it went from 0 to 3 ppm - did nothing). Is it a bad thing to have CYA this high? Will it go away over time as I use the pool or do I need to drain water? I'm hesitant to do anything b/c the water is crystal clear. What causes CYA to be high?
Thanks in advance for any advice!
