Wilco, I hope you don't think I was hollering at you. I work with school kids and tend to "teach" in most things I do.

You just want to make your pool better and to use the BBB method; that's great! BUT it can be overwhelming at first. The time and energy it will take now to learn about pool chemistry will be greatly rewarded. You will become more than a pool owner; you will become a pool OPERATOR. The freedom and the sense of accomplishment, pride, and control you will gain is your gift from PoolDoc. Accept this gift.

Here is what I humbly suggest you do:
1) Conduct all testing below using ONLY your K2006
2) Add bleach to get your FC to at a minimum of 10ppm
3) Perform an overnight chlorine loss test. ASK if you don't know how to do this.
4) Report your results clearly on this thread
5) Do nothing other than maintain FC >=10ppm until you receive a response
6) Do not bring up any other side issues in the meantime.

Others who are more knowledgeable than I may disagree and if so, I hope they speak up, but I believe we need to get back to figuring out why you are not able to maintain your FC with reasonable quantities of bleach.
