At least I'm all practiced-up

I was thinking the same thing, but if nothing else, it was a learning experience. I'll likely just do a 100% drain this fall, The guy at a local Leslie Pool told me he has seen no iron in fill water for people on city water, so hopefully the stain lifting will be a 1 time thing--and it really is quite minor, as far as how light the stain is, I'm just picky. He told me to bing a sample in, and he'll test it for metals.
