Hi, and welcome to the forum!!
It might help if you log out, go to the main forum page, and open the first set of threads in the second section, called chemistry for Intex pools. I realize your pool isn't an Intex, but the first sticky in that subforum, called " before you fill your...well water!" will apply to most any pool with metals in the water. Read through there, and if it doesn't answer your questions, ome back and post them, and we'll be glad to try to help.
