Great. That's an encouraging success story!

By the way, while it's not essential for safety or anything else, some people have a lower tolerance for any stains or water discoloration than others. If you are one of those, buying some HEDP and a CuLator baggie can help you keep it crystal clear continuously. What you'd want to do is put the Culator in your skimmer, UNDER a skimmer sock. Then add a 1/4 - 1/8 dose of HEDP every time you add water. The HEDP will keep the iron dissolved; the Culator will remove it.

If you don't want to spend them money, that's fine too. But you'll have a small recurrence of problems each time you have to add more water.
Deluxe Intex Surface Skimmer
HEDP is a liquid phosphonate that is pretty chlorine stable, and very good at keeping dissolved metals IN the water, instead of ON your pool surfaces. It can lift recent stains, OR it can be used along side of ascorbic acid, to keep the metals in the water, after the ascorbic acid is consumed by chlorine.

20% KemTek HEDP @ Amazon
The CuLator product is a special patented plastic material, contained in a bag that goes into the skimmer, that can slowly take metals OUT of your pool water. We think it works, and have some evidence that it does, but not proof yet. (Not likely to be available locally.)
