Edited my signature - let me know if I need to add more info.
I have a tendency to ramble, so I'll try to keep this short and to the point.

Using the BBB method to the best of my ability, and using the pool calculator.
My questions are:

1. I know I need to add more cya, but when will I see my levels go up? Aiming for 80ppm (live in Texas -currently 107 degrees)
2. Do I add bleach in the meantime even though it won't stay?
3. About how much will I have to add each day before the cya is up?
4. Don't I need to get my cya and pH correct before adding chlorine?

I'll take any advise.

5. Oh - and I was planning on adding just a little diatomaceous earth to my filter to help with smaller particles. Ok?
6. Should I be using di-chor instead of bleach? I read about someone using that.

Thanks again. Really counting on all your experience to get me through this pool season. Learning all I can.
