Thanks for answering me! I read the post you recommended, but still have questions ...

The pool store analysis (test strip through a computer?!) said we have no metals. I guess it is possible that the metals are either sequestered or mostly out because we have been continuously filtering through our sand filter and the extra "culligan" filter.

What I need to know is:
1. What is the best way to get the chlorine up to maintenance levels.
Super shock with about 10-12 lbs of dichlor (chlorine and stabilizer) shock. Or get it up slowly with separate CYA and liquid chlorine? I don't want to keep pouring chemicals and dollars in and having the chlorine disappear constantly.

Can you help with that question? My husband is going to another pool store today to compare their advice with what the other store said and what I've read here.

Thanks for
