If you think there is any chance of a water exchange to some degree, do that first so that you don't waste chemicals. Then SLAM. The AA treatment is all about cosmetics, so you can do it now or later, whichever works best for you.
Strange how it came back so fast..Mine has actually got a little better..I did add jack filter fiber to help my cartridge work better.@markayash -- I'm actually in Fayette -- I just use the Atlanta, GA location because I don't want to be too specific on the internet. I've asked on my local Facebook town page if anyone else has iron staining issues.
Oh wow, 10 lbs? I used 3 lbs of AA, and that got all of the staining up, it's just that it keeps coming back. I've added 2.5 qts of purple stuff at the initial treatment, and then three days later added another 1/2 qt, and then if I wasn't about to SLAM, then I'd add another 1/2 qt today. I read on another post here how someone had to do 8 qts of purple stuff, so maybe mine isn't so bad, it just feels that way.
Just talked to the husband about it, and he votes to drain the pool after the season is over. So, I'm headed for a SLAM today. We've had the ladder out of the pool to get it good and clean, but if I'm going to SLAM, then I'm gonna put that sucker back in so that all the nooks and crannies get clean for sure.
It would probably be OK BUT I wouldn't wait a day or 2 if you can. Is the pool dirty?
Is the smell from CC usually?
Does iron filter out better with high or low Chlorine?
I wondered that, this last time I added 2 qts metal magic and had nothing in my filter BUT over time the Iron stains have gotten better..I am keeping my FC down around 5 or 6 and PH below 7.6For us, it seems to be doing much better at high chlorine. But, from the reading that @mknauss posted earlier, what I think happened is that when I put the purple stuff in, that bound up the iron and made them not visible, and therefore not filterable. I think that the SLAM levels of chlorine has broken down the purple stuff, which released the iron (made it angry as per @Texas Splash ) and now the poly fill is filtering it out.
Also, we've been adding ascorbic acid on the stairs -- and it's been releasing the iron from the stairs. I know that FC needs to be low in order to do a true AA treatment, but we just wanted to get the iron off some of the really bad areas so that the polyfill can grab it, and it seems to be doing the trick.
But I'll feel more confident with that once I consistently have a true clean and sparkly TFP.
