I'm still new at aquatics and although I've been reading a great deal, and learning quite a bit, I have a million questions...like this one.

I understand (basically) how a protein skimmer works. The bubbles coming up make contact with water coming down and carries proteins out into a collection cup. Correct?

Does it only work with saltwater tanks? Why?

TIA,
