Is powder food harmful for corals?

[black_art]

Hi there,
Some people claim that powder food like "Reef Blizzard" has sharp corners so can be harmful for corals. I was wondering whether it is true or not.

Doubt this is the case. Just a light feeding of this food is needed.

Except there aren't any NaCl crystals in seawater.
