Closed Loop? What is it?

[cprdnick]

What is a closed loop? I get the general idea, but how is it set up, what benifits do they offer?

thanks kip. So you don't have to have holes in the back of the tank?

I know you do, but is it possible for me to do it without the holes?

You could go with hang on the back tubing or hoses, but the danger of doing that is you risk the chance of back siphoning
