Some time ago I read a post about an alternative to AA for iron staining I think by Swampwoman (not sure)
Can anyone guide me to it?

Hi Dennis. If it was me, there may have been extenuating circumstances, as the AA treatment is the go-to for extensive iron staining. 
However, I don’t like having to fight to bring the FC back up, so prior to my water change, had used higher doses of Metal Magic, with the amount determined by the http://www.proteampoolcare.com/images/uploads/MetalMagicSpongeTest.pdf
So that’s one alternate option that seems to work for some people - in the case of iron anyway.
My second shortcut or low-hassle stain treatment is spot treatment with a dishwasher wand or spot wand tool, but in this use I’m mixing AA with water and loading the dispensing wand with same.
If a poster has copper stains, I generally recommend muriatic acid or sulfamic acid treatment as more effective...latter is a bit of a hassle imho.
So let’s start with why you don’t want to use AA, if you’ve tested the spot, if your water source is high in known metals, and if you read for metals in your water. That will help get started on the best method reccs.
PS - I did do a rather complex and controversial experiment with alum floc as a dual high po4 and iron removal approach. There are a whole pile of caveats I would issue about that once - eg what is your filter type and can you vacuum to waste — but in my case it was effective. That one is a “do at your own risk” approach.

Thanks for that Swampwoman
I have previously done an AA treatment quiet successfully but it was a long job to get my chlorine back under control
Remembering your post I was checking to see if there was a more effective way of treating the pool water without the prolonged wait to get the chlorine in range
I have put a double dose of sequestrant into the pool and that has had some positive results with removing some of the staining but a bit worried about puting to much in
I also have the Purity Pool underwater acid wash kit which has been quiet effective as well but can only use about 1/2 a gallon at a time because of lowering the pH to much

Gotcha. I felt the same way about the full AA treatment Are you on well water?
Have you done the sponge test with Metal Magic? That will be your next easiest step depending on the degree of your staining.

No I'm on mains water and am 100% sure it's metal staining as Muriatic acid, ascorbic acid and LO-Chlor No More Metal does remove it
It's difficult for me to get Metal Magic here in the UK
