Test Results and Chlorine questions

[Watermom]

You can kinda work on all of these at the same time and it should be fine. Read the two links in my signature below about lowering alk and using muriatic acid safely.

Before we address the other questions about raising calcium hardness and CYA levels, we need to know what you are using as your source of chlorine?

EDIT by Watermom: After I answered your question in another thread, I discovered the very same question here so I moved the answer. Please do not double post the same question in more than one place on the forum. It makes it too confusing to try and help. Thank you.
