Sand or plaster dust?

[theCapstone]

New (2.5 weeks) pool. I’ve run the robot 3x since I got it Wednesday. Each time I get a significant amount of material. Looks like sand. Could it be plaster dust or is my sand filter putting out sand? Is it normal?

Diamond Brite plaster if it matters.

Looks like sand to me.

Put some vinegar on it. If it does not bubble it is sand. If it bubbles from the calcium in plaster then it is plaster.

Assuming sand. I’ll try the vinegar to make sure.

If sand is that amount normal for starting up a pool or could there be an issue with the sand filter?

What type of sand was used?

What model sand filter?

It’s a Pentair - need to check size and if it’s a Tagelus or Sand Dollar.

Watched him pour sand in but didn’t pay attention to what kind it was. I’ll reach out to find out.

Found that write up - thanks

I suspect Quikrete. I remember white plastic bags with some blue on them.

Reviewed with builder. He’s going to replace the sand in the filter with 20 sieve size sand.
