Thanks for the help. I have a 16x32 21,100 gallon pool with a SWG, sand filter, and 1hp pentair pump.
Other than ph my water was extremely close to clear on Sunday. I shocked last night with liquid chlorine and added 4 bags if salt. This morning my pool water was clearer but green. My CYA randomly jumped from 70 last night to over 100 this morning. I added some metal free today at the advice of Leslie's pools.....don't judge the newb. Tonight late I added enough soda ash to get to 7.6 ph by what my test kit booklet told me.
Test kit is a Leslie pool one but pretty sure it is the Taylor k-2005.
My last numbers
FC - above 10
TA - 100
CH - 90
PH - Less than 7
CYA - over 100
