Unipac Kivu Fine Sand OK for Panda cory?

[Wulfen]

I have read that some sand can be too sharp and may damage cory barbells.
Has anyone used this sand and can confirm if it is suitable for cory's?

I think the damage to their whiskers is more to do with infection than mechanical damage. But I have pandas on unipac and they have bred.

Many thanks Tech.
