Cool Tube Defect maybe?

Hey I just got a new Hydrofarm cool tube and noticed what seems to be a small rock or sand in the actual glass.So it creats like a pimple in the glass.Do you think I should return it or is safe to use?

the little piece of sand in the glass is just manufacture defect.It does not take away anything from the integrity of the glass.It will not take away from your lumens passing through the glass.It is perfectly safe
