I have had my pool 13 years, the first liner lasted 11 years and we installed a new one 2 years ago. The first 11 years I used pucks from Walmart and I guess they just had smaller amounts of stabilizer in. My cya stayed a little high but never over 80. (Maybe all day direct sunlight helped this?)The last 2 years I have been using 3" tabs from online pool stores and my cya climbed into the 150 range. So after being disappointed I now have the pool drained 60% and filled back up. I should be firing up the pump in an hour or so and getting some samples. I will be using liquid bleach/chlorine from here on out and only using tabs when stabilizer is needed or when I go away for several days(until they're gone, which will be awhile). How often do you guys add bleach? Everyday? Every other day? I guess my first thing to do is determine how much the pool uses a day. So now I am on to a new learning experience. Up until the last week or so all of my water tests have been great and in limits since I check every other day.

Well my TF-100 is on order. So I added some baking soda and I will re-check in a few. Gonna bump up the FC 1 ppm, I am interested to see how much bleach it uses a day since it gets full sunlight all day.
FC - 4
TC - 4
TA - 40
PH - 7.0

Welcome to TFP!
Most pools use 2-4 ppm FC per day. Have you added any CYA to the pool? It will need to be at least 50 ppm for your climate. Waiting for pucks to get it there will take too long and the sun will burn off your FC too fast. Put some in a sock and hang it in front of a return.

CYA is 50 according to the strips....which I know suck, but I have been using them and a 5 bottle test kit. And comparing the two. It has worked for 13 years but has failed me this year with my CYA so high. My TF-100 will be here this week.
Chlorine level is set based on the CYA level and the [FC/CYA][/FC/CYA]. So, with CYA at 50 FC should be at 6 ppm and never drop below 4.

Welcome to TFP! Good to have you here. Sounds like you're well underway with TFPC. Good decision to take your CYA down with the drain/refill.
All trichlor pucks have the same ratio of FC to CYA, which makes me wonder if your old liner may have had a slow leak in it which allowed you to keep your CYA level down with gradual water replacement.
