Thank you Waterbear and CarlD. I've read many of both of your comments on this forum already. You knowledge has been very helpful already in filling my knowledge gaps and debunking some of the bad advice I've been given.

The pH test is the standard 5 kit done with the reagent drops, yah not a pH titration, and I do have an acid demand test available.

With regard to the CYA results on the test strip they are much closer in color to the 50 ppm than the 100. I don't know if that information is helpful. I've never intentionally added CYA to my pool, but it's something that I started to take note of after reading this site and since than have realized it's in the bag-o-schocker from sam's club that I've been using on my pool once a week (only in summer) per the pool store and pool company experts advice.

I turned down my generator percentage for the chlorine. We'll see tonight how that is going.

Also, one more thing. I added the DE to my sand filter and have had to flush it out twice. Starting with a 15 Lb running pump pressure. I added a slurry of DE to the skimmer and increased it's pressure by 1.5 -2 Lbs and I left it alone (now running at 17 Lbs +/-). The next day my filter was running over 30 Lbs. Initially shut off the pump, shifted the flow to backflow, but changed my mind before turning it back to normal flow and turn the pump back on. I noticed that the jets were then jetting a slight cloudiness into the otherwise clear pool that hadn't been happening before I messed with it. So I back flushed and tried again adding the slurry of DE with the exact same results (ie initial success but 12 hours later pump runs up over 30 Lbs) Tried again last night and will have to wait till this evening to see result since I'm at work today. I know this shouldn't affect pool chemistry, but I can't discount the affect millions upon million of tiny glass skeletons potentially attaching to my skin might have.
