I've had an 18x36 Pool for the last 14 years and I have acquired a new problem... About 3 weeks ago during spring startup I noticed a brown stain on the steps of the pool. We shocked the pool and the next day the stain was gone. The stain has now returned and is present throughout the pool. I did the vitamin C test and it appears we have iron in the water... Where could this come from after 14 years? Is this common ? Reoccurring ??? Thanks for any input...

Yes, the same one that has been there for 14 years. Could that be the problem? I have noticed some corrosion around the ladder lately..
A very likely suspect!
If you see corrosion "around" it.........there's probably more "in" it.

Often iron levels build up slowly over years until it reaches a level high enough to stain the pool. Common sources can be a ladder/railing or well water with trace amounts of iron. A plastic or stainless steel ladder will help. Although 14 years is a pretty good run. A partial water change will reduce the iron level in the pool, if the source of iron isn't your fill water.

I would identify the stain positively first. That it was removed when you shocked your pool is not indicative of iron but rather organic staining.
Shock process will normally intensify iron staining and certainly not remove it.
I would suggest you post a pic of the stain and place a puck on it for a few minutes to see how it reacts

The first 2 pics are the rust on the ladder. The next 2 pics are the stained steps. The area at the upper left corner is where the vitamin c was used to clean. A puck was also placed on the step in a different area and there were no changes to the stains.

That's pretty obviously iron. It remains strange that shocking the pool removed the iron.
I don't know but I think it would be prudent to get the ladder out of there and see. What is the source of your refill water?
I assume you've had the well for as long as you've had the pool---------like 14 years. And THIS is the first time you've had any staining? Doesn't make any sense to me.
Can't the quality of the well water change over time with different conditions such as drought or something?
Do you see any iron stains in your toilets also?

Never had a stain in 20 years of living here..

How soon should the area that I cleaned with Vitamin C go back to being stained???
Fiberglass attracts iron stains. Eventually the stains will return. Adding a maintenance dose of good sequestrant will help slow it down.
Just like CH continues to build in a pool, so can iron until it reaches a level where it precipitates.
