SLAMING my neighbors pool

I am trying to help my neighbor clear her pool. She has a vinyl liner 26,000 gal pool. Cartridge filter and Trinton whisperflow pump. Her old pool guy has a blue mineral unit in her filter basket, which I had never heard of until I Googled it. She has also shocked her pool a few weeks ago and it did nothing but turn it a bright green color. I am trying to find a place in town today to test her copper levels after reading several threads on here about high copper. Plus some of her blonde daycare kids hair turns green or did last season. So thats why I am suspecting high copper?

We are started SLAMING yesterday. I had her bring up her cya to 40 first a few days ago, now we are keeping the pool at shock level of 16, her cc's is .50,
TA 140
CH 50
PH 7.2.
CYA 40
I have her filter running 24/7. Here are pics of her pool. Can anyone help me identify the stains on the stairs? And I should I be doing anything else?

Hey Mr. S !! Here’s a refresher cuz it’s been a while since you did it last: SLAM Process. The PH is perfect to start so SLAM away.

The cliff notes are to keep it at SLAM levels based on the FC/CYA Chart. Every minute counts so get over there and test/add as much as possible. The first day or two is the most important. Every 2 hours will make it go that much quicker.

And GREAT on you for being a helpful neighbor!!

Tell her membership # 253,216 is hers for the taking if she wants it. :)

Be careful - SLAM level FC could really push the copper to stain. I suggest a healthy water exchange before anything. That bright green you saw when you added the chlorine was copper. Only way to get rid of it is to drain and replace.
Throw the mineral thing away. I suspect she all ready has some copper staining. And a vinyl liner pool, it is best to replace the liner to get rid of the stain.

For financial reasons she wants to get more year out of the liner, it doesn't look terrible but I am worried about her stairs, those don't replace easily. So high FC will set the copper stains? Yikes!

She just spent money on CYA and all this chlorine so replacing a lot water might scare her off.....would Jacks pink stuff work at all? Ugh. I am very confident in the TFP method but I have to be careful how much to push because she's never had issues until last year. 😬

The Jacks is sulfamic acid. It might release some of the stains, but then you must drain the pool to get rid of the copper. And the sulfamic acid will disrupt the FC/CC testing for quite some time.
