Thanks for the quick replies. I know that you cannot drill these tanks however and while it has been done its risky. I'm kind of leaning towards the canister like I described above, but now I'm thinking that maybe I should go with the 2217 (http://www.drsfostersmith.com/produc...03&pcatid=3603) since it would hold a bit more water and provide a lot more flow. Does the media I described above sound like a good plan? And will the liverock really be beneficial if kept in there as well?

I also think I'm going to go with the viper, even though I probably won't keep any SPS.
