That depends. With marine, you generally have live rock and a protein skimmer to help out as well. You can actually filter a marine tank with live rock and powerheads if you know what you are doing and stock properly, etc. So without knowing more about your set up, I don't know if the Penguin 200 will be enough to start you out, but if that is ALL you have, then no, it probably won't be.
The Magniflow comes with foam blocks, carbon, ceramic rings, and bio balls. I would add additional media to the Penguin filter as it comes with the bio wheel and uses replacement cartridges as well. However, it has enough room to add something else so I would add additional media in the form of ceramic rings, bio balls or something similar, in a media container or even a nylon stocking.
If you plan to have corals or anemones, I would not recommend using the carbon. I'd replace that with more biological media.
