Had forgot about testing my CYA for a long while, noticed I was adding alot of chlorine and it would quickly go to 0. Tested just now and double checked at pool store and yep, 0 CYA.
CC-1 (in the middle of shocking after leaving for 3 days)
CYA - 0
CH- 220 ( will raise after cya us under control)
TA - 80
Is the sock method the beat way to add it? It says to add 9 lbs but I am only going to add 4 right now and see what it goes up to in a week. So can I do 2 lbs in each sock in two skimmers.
Can I continue to shock while adding cya. Pool got away from me because I added what I though was enough clhlorine for 3 days, but with CYA At 0 and temps of 102, the spa as yellowing when I got back. Looks all clear now, just a little something still eating the chlorine.
