I just received the TF100 test kit to try and figure out why I can't hold chlorine in my pool. I have a 24000 gal vinyl liner pool in MI. I do not trust the pool store anymore so decided to take the advice on this forumn and go it by myself. I have an inline chlorine dispenser but have decided to try the bleach method and see if I can get my CYA levels to come down.
First check, CYA 80 FC .5 CC 3. I know that is bad and probably why I can't hold chlorine. I added bleach per the pool calculator last night to bring FC to 21 and will check again this morning and add more bleach as necessary to maintain FC at 21 until CC are below .5.
Question, my water is crystal clear. Is it normal to have CC so high but the water so clear? I did the test twice about 8 hours apart and had the same result CC = 3.
Any help/advice is appreciated.
