As I feared, would really like to get Fe out. Have been using BBB method for years. Did great until liner need replacing and could not get anyone to deliver water this time in this very rural area.
I have Taylor K2006c & K1000 test kits
Pool Specifics:
IG vinyl; 22,000 gallons; sand filter, 1HP pump
FC: 5ppm
CC: 0.5 ppm
pH: 7.6
Ca hardness: 80 ppm (turns purple, not blue)
Alk: 160 ppm
CYA: 70 ppm
Plan to decrease pH to 7.2 with muriatic acid tomorrow
Will get the polyquat
No stains currently-removed with Vit C
? past point for a Culator or do they even work?
Thanks for your help.
