New Pool Owner - true definition of newbie!

First time pool owner. We opened it July 7th. It's a chlorine pool - 16X30 with a 3 foot tanning shelf, 2 steps down, 3 foot depth, to a 5.5 deep end (with an upside down cone to the deep end) - I'm sure there's a fancy name for that - but I'm not sure what it is. We have an auto cover that is installed under the rim of the pool (which we really love). Since we don't have a fence, I'm paranoid to leave it uncovered for any length of time. So, it's probably closed more than it needs to be - but with kids in the neighborhood, I don't want anything to happen. I have an inline chlorinator, I was using 1inch tablets, but when they ran out, I've switched to 3 inch tablets. Still getting the chlorine dialed in, it's been at 10ppm for the last 3-4 days, but I'm hoping for some sun burn off to lower that a bit. We live in Central Indiana, we have a heater, we'll see how late we keep the pool open. Some years are 80degree Octobers, some years are snow before Halloween. I purchased an automatic water tester (Sense2) that seems to be a good way to test. I know people hate test strips (me too) but I've already purchased the automatic reader, so I'm hesitant to also spend $117 on a test kit. We have a Aiper robot cleaner - which does a decent job, but it doesn't like the slope - and it doesn't do a good job on the corners. So, I manually vacuum as needed. I'm sure there are a TON of things I'm missing, and possible doing wrong, but as of yet, no one has run screaming from the pool with their skin peeling off, so I think I'm doing OK. Looking forward to learning from the group - I've heard LOTS of good things on social media, and so far, I've gotten really good tips!
