I have the Red Sea roller mat and it is an impressive tool (probably the best invention since the protein skimmer IMO ).It was far superior to the theiling mat I had before it. Also, you can just purchase a DC pump for your skimmer….I recommend sicce PSK pump, I use it and am really happy with it. Also, you can check out either of these on my tank if you want to see them in action.
