Hard Bumps on Inside of Skimmer?

[CC13]

Hey guys,

Not new at all to reefing, but I had a quick question. I took apart my skimmer today for service (Vertex Alpha 250) and notices there are tons of tiny little 'bumps' on the inside of the skimmer.

Sort of like those tiny bumps that start to grow over time on mag-floats if you leave them in the tank.

Question #1: Should I remove them?
Question #2: How to remove them?

I know when I got the skimmer and it was new, the acrylic was completely smooth.

Thanks!

They are normal, small calcium deposits likely from tiny worms. Vinegar soak for a few hours and the skimmer will be as good as new.
