New to BBB, what next?

I understand not caring about calcium for a vinyl lined pool (wish I would have found this site years ago and saved hundreds...) but I don't need to care about alkalinity as well? It is 70 now and the ph 7.6, Cl 2.0 and CLY is 35. Thanks

It's not so much that you don't need to care about it at all. It's just that it's usually not as big a deal as pool stores say. If your pH is OK and stable, and you don't have a concrete pool or heater . . . your alkalinity is probably OK where it is.
