I picked up a 90g setup the other day, and though it came with a used sump, I recently bought a 20g tank and a protein skimmer that I don't want to see the money go wasted. My questions are:
1. How do I set the protein skimmer up to the tank, and how does it operate?
2. How do I create a refugium inside the sump?
