My numbers are:
1 2 FC
2 4 TC
1 2 CC
200 calcium hardness
First, I don't understand the 2 numbers on the Chlorine part of the tube. Does 1 2 mean it's between 1 and 2?
Second, I now know my CYA is so high because of the trichlor tabs I've been using. I am going to drain some and refill. So how much bleach do I need to add every night to maintain a level of 3 FC?
I also have a little bit of algae in spots. I think I saw on this site that algaecides don't really work. Is that true? Will the bleach alone kill it?
Thanks for any help you can give me! I have been battling low Ph and high CYA since we built the pool 2 years ago and I knew something wasn't right but didn't know what. Pool stores were no help at all. Thanks again!
