Two words: Pool Bot
Get one. It'll pick that screw up and make your life easier in general. I have this one

As for chemistry, I don't get the grief here. I get my stabilizer set and then it's just cake. I take my readings in the evening and add chlorine using one of the two tube testers (chlorine/PH) and once a week I break out my titration kit and check free chlorine and test for combined and shock if the combined shows I need to. Easy Peasy.
BTW, it seems I rarely have to adjust my PH but it's all pretty easy if you download the Trouble Free Pool app, punch in your readings and then use the recommended levels.
