I added approx 2lbs of cya(hth brand) I tested ahead of recommended sched as realized the filter had not been cleaned and needed to do so before company on July 4. So I tested that am and cya just abov 30 ppm. Not bad but below min recommend. So I added about a 3/4 lb more to a sock and am letting is come up slowly. I will test in another week. The chlorine seems to be doing well and the ppm drops, but slowly from one day to the next. So I am feeling confident that I am getting a good balance of chlorine and stabalizer and will add just a little more cya slowly as described above.

The alkalinity is the shocker. I have added nothing to the water and have a 200 ppm alk. This explains my Ph being so steady. I live in an area noted for it's hard water, we all have water softeners and run lime-away through our dishwahers 2x a year. I know muriatic acid can break down the alk but also lower the Ph. I am inclined to leave the Ph alone for now, but am concerned about scale over time, especially in the filter. Maybe I need to attach a water softenter to my pool.

We had a large 4th Jul. gathering and had about 12 people in the pool which a lot for a 12x17 pool. The water is a little turbid this eve. So I decided to shock the pool. It's a good afternoon to do so as we have t-storms, wind and cloud cover so nobody will be swimming this eve. I did this and ran the pump and already it is clearer after 1 hour.

Overall, I am feeling pretty good about what I am doing and how the pool is performing. But if any suggestions based on this come to mind, let me know.
