Filter rollers linting???

[Alwaysmoretolearn]

Hey,
Anyone have this issue? Been running bubble magus xl filter rollers for about 4 months. Noticing what looks and feels like lint accumulating on my brightwell xport bricks. Any ideas? Btw...can't imagine it would be the bricks themselves, but the bricks are probably 8 months old.

Is it actually pink?

Wow that looks like factory made!
