Welcome to the Pool Forum!
Thank you, I didn;t realize there was a delay and thought maybe I hadn't clicked submit on the first one.

Thanks for the feedback, the "HTH Super" will go back to the store tomorrow and I will find the Tri-chlor! Tri-chlor was what I used all summer and my CYA levels are in range. I will watch them next year to make sure they don't get higher. I have an in-line flow controlled cylinder for the tablets so I can fine tune the baseline chlorination and CYA, then shock as needed.

As for Algaecide, I just found another gem on this site and figured out why I had to shock my pool 4 times on Sunday just to get a measureable FC level . . . I put in a treatment dose of Algaecide on Friday (NOT polyquat, cant remember the long name) and it was probably eating the chlorine.
