HELP pebble erosion due to shock?

[Sammykaggie]

This might be the wrong thread here but I made a mistake. I put cal hypo packets of shock in my pebble pool and don’t brush it well. It was before a party and I just forgot. Now there are rust stains all over my deep end (but also in other places). Did I erode my pebble so badly that the rust is coming from the inside? Is it rebar stains?

I’m freaking out that I might have caused thousands in damage. Do I need to contact the pool company? What should I do?

The only other thing that I have done different is get new filters and then the pool store convinced me (finally) to get a phosphate remover. (I know how we feel about those on this forum

I did put a vitamin c tablet on one of the stains and it lightened up. I tried taking a pumice stone to one of them and it did nothing except wear down the pumice stone.

I think you have iron in your water and the sudden pH change from the cal-hypo caused the iron to precipitate out of the water and deposit on your pebbles.

Nothing structurally is wrong with your pool or rebar.

Any idea where the iron came from in your water?

Where is your fill water from?

Water in Katy TX has iron in it. Normally is not a big problem as you get lots of rain such that you do not need to use much fill water.
