SWG and pool

[waterbear]

Have you tested the water for metals? Also, even though it is a vinyl pool the cacium hardness can be a factor, especially for metal parts....what is yours? If it is below 100 ppm I would bump it up a bit. If the rusting seems to be at the screws it can be that they are not stainless. A seqesterant in the water can have anti corrosion effects. might be worth a try also....just some thoughts. are you sure the brown lumps you are seeing are rust? Doesn't sound like it to me from your description.
Finally, I would use muratic acid instead of sodium bisufate with a SWG. No need to be adding sufates to the water.

Update...

Brown stuff still appears and is not magnetic (used a magnet to try to attract it, nope)

Seems that is is a few SS screws, that I can try to replace and at certain areas where SS panels are just separated by 1/16 inch --> <-- right at that point this brown fluffy stuff "now I am not calling it rust because it might not be ?"

Still need to have water tested for metals.

1
Does the fact that SS metal benches that are in salt water, at 3000 ppm, is there some protocol to connect this metal to a ground bond point?

I just do not know about this. Are all ladders and metal parts typically connected to a ground bonded point in pool construction ? what type of connection is used to connect the metal parts ?

2
Does bonding or could it, get rid of some "electro" action that might be depositing this fluffy stuff ?

The pool construction is a metal panel with liner. would connecting the interior SS pool benches make a diffence?

Thanks in advance for your help,
