Found pool math app yesterday. Where has it been all my life 
28,000 gallon liner pool, auto cover, and cartridge filters. I use a taylor k2005 for testing. I shock with 1lb bags weekly and use 3" tabs in my chlorinator. This is my 8th season with this pool and it's never turned green on me.
I have also never maintained FC. It's rarely over 1ppm. I learned today that it's caused my CYA being zero or close to. Not sure how I've been this lucky all these years, but I'll take it.
My goal this year is to get my CYA up and maintain FC using liquid chlorine.
