History:
Pool liner and filter both 7 years old.
Topped off as needed with water from Kinetico treatment system as we have high iron content/hard well water.
Tested regularly by pool store - no metals noted. Ph does tend to run high in this pool but we are working to monitor and balance as needed.
Water is crystal clear/blue BUT starting this season, upon use of a "new" product recommended by them called "EZ Pool" (All in one algaecide, shock, etc.) We now have yellow tinge staining around the perimeter of the walls/floor and brown stains in splotches on the floor.
Upon first appearance pool store recommended stain remover, scrubbing, lemons (!) and removing all chlorine and taking pH super low. Pool stains did clear up. We also replaced all sand in filter as a precaution.
We followed their lengthy recommendations to a "T" and all was well with the chemicals (per their advice) until we added the EZ Pool again. Three days later - stains are back!
I'm beyond frustrated because we are following their advice (and have a good track record with them overall) but it seems like endless $ on my dime to play "well let's try this ..." without resolution. I'm particularly peeved because we had no problems for 6 years. My water chemistry did not suddenly "change" this year. We obviously will quit using the EZ Pool ($199 bucket by the way).
Does anyone have experience with removing what appear to be yellow/brown metal stains without spending a fortune or requiring a chemistry degree? More importantly, how to insure that they STAY gone?
I can't prove it's the EZ Pool but I'm skeptical that after 6 years of trouble free maintenance we suddenly have a high maintenance pool?

This makes me think I might be wise to follow the advice help-with-copper-stains-t12242.html I know it's a few years old but I can't imagine the information has changed much? The issue being I am not known for my patience and have no interest in waiting "a few months."
As of 7/22 I'm placing a chlorine puck on the stains and they are disappearing. I don't think they are gone - I think I just bleached the scaling/stain and it will likely reappear (think stains on a toilet bowl. The scale/buildup is there - but the bleach makes them "disappear" temporarily).
My question now is have we been on the wrong track all along? If they fade immediately in chlorine (but bounce back if it drops) and do not react to metal stain removers - are they organic after all?
We are boaters/lake swimmers and one fear I've had is that something was introduced into the pool from the kid's bathing suits? The only issue being that the timing of EZ Pool = "Bam! stains!" seems too perfect to be coincidental but I'm not one to place blame if it isn't there either.
