I did follow HTH's advice. Their final advice was to take my water to pool place to make sure I was adding enough Metal Control. Pool Doc, the pool place told me to upgrade to a sand filter. The 2 women working at the time said that they actually have intex pools(bought from walmart), but use sand filters for the same reasons you stated in previous post. None of them have iron in their water though.They sold me a product called Metal Treat. it contains: Tricurboxylic acid/Phophonbutane. My question is that if i actually add the correct amount will my water turn brown after I add my chlorine. I got my intex pool for free, so if I can't get it right soon, it's coming down. My other question is, if i start using a sand filter, will that take the brown that's in my water now out? If the filter is the trick, I'll go that route. For some odd reason, most of the pool places around me don't have a clue about what to tell me. I do come to this site for tips, then i was asking HtH about them. But, like I said, they didn't have any more advice for me.
