I don’t see my post, so I re-wrote it. Sorry if it comes twice.

Thanks Ben.
Hello everyone. I did the 50/50 tap water cya test and the black did not disappear. I will shock tonight and report in the morning. I do have a few basic questions;

1. Once the pool is stabilized, will I use more bleach than someone with a low cya? I understand it will take more initially, it’s after that point I’m not sure about.

2. Once stabilized, when is the best time to check/add bleach each day?

3. Any thoughts on what the bad smell is? How do I treat?

4. What is your best guess estimate on my daily bleach consumption, I under stand it’s just a guess-timate? My pool is a 12k in-ground vinyl and has sunlight all day? If it’s going to be more than 1 gallon per day, I think it’s best to do a few partial drain/refill now and get it done, do you agree?

5. If you agree with the drain/refill plan, how many times should I do it, and how much do I let out per drain/refill.?

Thanks everyone, sorry for the basic questions.
