CYA/crystal clear green water

[purplegirl]

how high should i keep the chlorine to help nix the iron problem? I'm curious does CYA usually occur naturally or does it always need to be added? When I filled the first time I had a 0 CYA reading, should I expect I will I have this same problem?

CYA doies not occur naturally, you're going to have to add it each time you start the pool up. However, once you get it up to your target, the only way to lower it is drain/refill, so be careful when adding it not to overshoot.

As far as managing water with iron in it, read through the metals forums, particularly any thread/post by mbar, to get an idea of what you'll need to do. High chlorine levels and high pH levels are going to make the iron tend to drop out of solution, so it's going to requre regular doses of metal sequestrant to keep the metals suspended in the water and not discoloring your pool.
