I thought about using one of those, in fact when I first saw them, i thought they were a surface skimmer for the 90xx family. In fact, they look like they might be easy to modify into a form of prefilter for the protien skimmer.
While I'm thinking sbout it, what's your opionion on using a reefpack 200 on a 50 gallon tank? I know it's the top of its size limit, but I'm going to a mushroom,zoanthid tank with a very light fish load.
