pvc questions urgent

[yellowtail]

the pvc i got has blue marking on it stating its size etc obviously printed from the factory. i think that this comes on all pvc.
is it ok to put in the tank and use it as supports for eggcrate racks with the lettering on it or do i have to sand it off?

It's okay.

It will be ok just be sure to rinse off the PVC as hardware stores have tons of sawdust floating around.
