Thanks for the reply Waterbear! I have been looking to see about the ascorbic acid and the salt water generators.

rwkellyjr,
You will probably need very little ascorbic acid - the less the better, because the extra will just have to be eaten up by the chlorine - that's why it's hard to get your chlorine to be stable at first. Just go around the sides of the pool with a small scoop (like one for coffee) and pour it heavier where you see the stains. Let the water circulate till you see all of the stains are gone. If they aren't gone in an hour, put a little more acid in. Make sure you put the sequestering agent in, then when all the stains are gone put your filter on filter again. You can start to bring your ph up the next day, but don't take it any higher than 7.2 or 7.3 for a week. After 48 hours you can start to raise your chlorine level back to normal slowly. If you have a sand or DE filter you can put a trichlor puck in the skimmer basket, this way if the chlorine is going to stain, it will stain on the filter. Don't shock the pool for at least 2 weeks.
