Hello Everyone,
I have a Chinese Elm that I recently repotted and is doing good, but I just started noticing white (almost seethrough) rocks near the roots. Some are really small and look like fine salt and some are a little bigger and look like cooking salt. I attached a few pics of them.
Can anyone please tell me what they are and if I should worry?
I am new in this world and I can't find anything online about it.
Thank you for your time and help.

Looks like Akadama to me!

Can't really see the white translucent salt crystal like sand in your photos. But, my guess is it is perlite, which is not uncommon in potting soils. Nothing to worry.

Looks like normal grains of sand.

Thank you, everyone!!
I am sorry the pictures were not as clear, but I am glad it is nothing bad.
Thank you again for your help
