That adds copper and copper will stain the pool.It does have the mineral cartridge according to Google.
I would remove the mineral cartridge.
Copper complicates the issue quite a lot.

You can only remove it if there is the dummy plug available. If that isn't still with your pool supplies, then you'll have to bust out the minerals and put the empty mineral container back in. The mineral cartridge is part of the lid for the Fusion Soft.It might help and it might not help, but it can't hurt to remove it.
So, I would remove it in case there is still copper and silver still being released.
Did you try to brush it away?The first photo is no stain. Second photo shows the stain. I'm not good with colors, I just know the stain is different than the surrounding plaster and not blue.
Before adding the salt and acid, there was nothing there and nothing else happened. No water was added to the pool, or anything else.
I'm not sure how it could be iron unless there is very small amount in the pool and it concentrated where the salt clump was. There is no return in that area.
Muriatic spilled on the concrete decking and made a similar-looking discoloration.
I used vitamin c tablets before to try to clean an iron spot. The iron spot went away but where the tablet dissolved there was a new stain. And I haven't been able to get it to go away.
What would you try? This is on the bottom in about 3 1/2 feet of water, but there is another stain like this in 6 feet of water at the bottom.
