Question from a Sump Newbie

What's a CPR overflow?

My skimmer has a small overflow box hooked to it. This is in the tank and the powerhead that feeds the skimmer in in the overflow box. I figured I could just get / make a similar over flow box for the sump / other tank.

Before all the questions start about "Why do you have it set up that way?", a bit of background. I bought the whole setup a couple years ago from a guy I worked with who no longer had the time to take care of it (never did a good job IMO). He bought it from another guy a couple years previously. It is my saltwater learning tank. Now, thanks to all you, I am on to the plumbing chapter.
