Pump, sand filter, heat pump, salt cell then back to returns. That's all the equipment that is back there.

They do not say that muriatic acid drops calcium out of suspension.
The person says that sodium bisulfate helps drop calcium out of suspension.
The person is incorrect unless you add enough sulfate to create calcium sulfate.
So, the statement is not 100% wrong, but it is it bad advice if they are trying to increase your sulfates high enough that calcium sulfate begins to precipitate.
In any case, if you do the test with distilled water and 200 milligrams of the precipitate, the TA and calcium hardness should be about 200 ppm when you test the water if the precipitate is calcium carbonate.

Ok I'm gonna try to do that. I will say over past 12 hours less is gathering on the flat surfaces. So I'm gonna let it build up a bit and see if I can get that much.

Liquid chlorine and muriatic acid are perfectly safe to use as long as they are used correctly.
As far as why someone else is saying that it's a problem, you need to ask them.

Is the pool manufacturer trying to get your calcium to precipitate?
Fiberglass pools have had chalking and discoloration issues for decades.
A handful of people at the manufacturer might know the real reason why the discoloration happens, but most people do not.
They don't want anyone to know everything that they know including most of the employees at the company.
They intentionally create a lot of confusion by throwing out a lot of misinformation about what the cause is.
They have blamed everything from liquid chlorine to sunspots.
Their claim that they have evidence that muriatic acid causes discoloration is complete nonsense.
If the acid is directly applied to the surface, then you can have problems.
For example, if you add acid using the "Slug" method, it will cause problems.
Properly applied, muriatic acid causes zero problems.

The pool manufacturer did say that it's an ionization issue with the cobalt blue color. That it attracts and allows calcium to attach to it very easily because of the ionization of the cobalt and the calcium. But I don't think we're supposed to know that. Was at a different pool store today and he stated the same thing without me even bringing it up. Not sure there validity to it but that's what they both said. But Im not sure that's causing the powdery substance collecting on pool surface. Gonna try to gather some material out of pool in next few hours to do the test that was mentioned earlier.
When I first saw your thread, I was going to recommend this lady. I hear that she's pretty good. However, now I suspect that you're probably not looking for her type of service.
Muriatic acid has only hydrogen and chloride.
Hydrogen just changes the pH.
As long as you are not dropping the pH too low, it's a non issue.
The chloride is the same chloride that is in every pool.
If chloride is a problem for their surface, then every pool is going to have a problem.
All pools have chloride, especially salt pools.
All chlorine adds chloride.
Their claims are complete nonsense and fabricated out of thin air.
Ask them to explain the exact chemistry they think is happening.

What attracts and allows calcium to attach to it?
What is ionizing the cobalt?
Their claims are specious pseudoscientific nonsense fabricated to sound plausible and scientific, but they are completely worthless.

I believe what he was saying.....maybe ionization is wrong term....that the cobalt has a negative charge and the calcium is a positive charge therefore the calcium gets attached to the sides of the wall easily. Once again really, at this point, just trying figure out the white stuff on bottom of pool and from keeping it from coming back.

My scale only measures in whole grams. 1 gram is as low as it will go. Can I just do 1 gram and test ta and ch?
