Pool is 20k. My first summer warm up. I'm in Texas, didn't expect this using liquid chlorine to get my CYA to 50. I started using tabs again 2 weeks ago.

I've wanted to do a side by side comparison of correlated vs secular history for a long time. Last night I started it, here is the first rendition of screen shots. Eventually I will post it as a website, but it isn't ready. I would love feedback from this community. I am happy to share the self contained .html entirety with anyone that is interested.
