Well Water Iron Staining

[wmarq]

Hello forum.

Looking for suggestions please.

Pool has well water autofill. Ive enclosed pics of inlet and outlet. Iron staining is pretty bad, always has been. These pictures believe it or not show improvement. I used SC-1000 this summer for the first time and it worked very well. It lifted more than 50% of the iron stain off of the wall in the picture and it has turned the pool cleaner and equipment back to white. It was stained just like the wall and inlet cover. The suggestions that I am asking for are as follows:

1) Suggestions for the lowest maintenance way to stop the iron before it gets into the pool at the inlet picture that I posted. (attached some kind of filter if it exists to that water line in the photo)

2) Suggestions for removing what is in the water. ( I know the SC-1000 has it suspended, but I am pretty sure that is still in the water just waiting to stain everything once more)

3) If the best solution (best solution defined as lesser maintenance and less expensive) is just to continue using the SC-1000 and keep the iron suspended, then I would like to know that as well.

Thank you in advance for any suggestions!

A couple things I would start with:
1 - Orenda makes good products, but I don't believe the SC-100 is pure Ascorbic Acid. Their SDS lists ingredients as "Trade Secret" which is always suspicious to me. So you might consider purchasing AA in its purest form and doing an AA treatment to remove the stains. But as you noted, either product simply pulls the metal off the pool surfaces and places it into the water. Then you have to decide what do do next:
a - Deal with it and continue using a sequestrant
b - Exchange as much water as possible for non-iron water (ideal)
c - Try to continuously filter with polyfill or any other product proven to capture iron.

The trick about filtering iron is the density of the filter product and particle sizes of the iron. Polyfill in a 5-gal bucket or other container, continuously allowing water to run through it, can be beneficial. It's relatively inexpensive and just takes time. I would start there after a good AA treatment if you can't exchange water.

if I cannot filter it out before going into the pool then It seems the easiest would be just to keep sequestrant in the water
