It sounds like you're describing mineral deposits in the water that precipitate out in the water heater due to the heating of the water. Then they get swept up into the tub when you run the water. Are you on a well? or does the town water supply come from a well?

No well city water...

Does your town get it's water supply from wells or a reservoir?

Customer: replied 1 year ago.
Reservoir
Expert:  Rick replied 1 year ago.

Have you called the water department about this? The only likely source is the town's water. There's nothing in the plumbing system that would/could produce what you describe.

Not a potential degrading diptube? It's only the bathroom tub faucet hot water only. We are not experiencing this through any other faucet in our home
Expert:  Rick replied 1 year ago.

Dip tubes are plastic. What you describe doesn't sound like plastic. Not to mention the problems you would have getting adequate hot water if the dip tube was failing. You probably don't get this through the other faucet because the flow into the tub is far higher volume that anything else in the house. So sediment is more likely to be noticeable there.
