After you do the stain removal, if you do a water change to lower your Ch you will be removing much of the iron tainted water from your pool and reduce the risk of restaining. Untill you do you will need to add a maintenance dose of sequestran weekly to monthly.Quote:

Too late now but, IMHO, the best way to do all of this would have been the stain removal, water change, and then lowering of TA.
At least I'm all practiced-up :D
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.
