Stay the new course?

Sounds like I am on the right course, just not using the right quantities.

I bought a Taylor K-1005 kit before I found this forum. I figured I would need a K-1515 if I ever get the chlorine over 5ppm.

We have a solar heater and I have it set to max out at 83 when we like to swim in the late afternoon.

I have been using 31% MA but never added more than 1/3 gal at a time. That was the first and only time I reached 7.6 pH. Since then I've only used small amounts to keep the pH just below 8.0. I'll start adding more to get to 7.6.

I have been using 12.5% LC from my local pool store but again I don't think I've ever added more than 1/2 gal at a time. I've followed the advice to add in the evening; I'll start adding more and keep a close eye on the ppm level.

To manage your pool, you need BOTH the FAS-DPD test AND the CYA test. Your high CYA *requires* higher chlorine levels -- read the Best Guess page page, linked in my signature.
