I agree. If you have a vinyl pool, the T/A is acceptable, still under the 200 limit, but a little too close for my taste. If pH goes up for some reason, T/A will pass 200. Still, as Dave says, no rush to lower it. CH is good.

With an FC of 4 and a cc of .5, I'd shock it up once more and then look for FC to be around 5 generally. I know the Best Guess says 30-50 CYA means 3-6 FC, but with CYA at 45, you might want to stay closer to the top of that range.

Beyond that, I consider your numbers to need routine adjustments, no more. Congratulations! Enjoy your pool!
