Question: Can sand too fine kill an axolotl?

[Kizu]

I have bought this silica sand which is almost powder fine, is it bad for axolotls? I've read that the finer the sand is the better as it reduces the risk of impaction...

Should be pretty harmless unless it clumps together when wet. If it does that, then there is a high risk of impaction if your axolotl ingests the substrate.
