I'd go with all poret foam on media in a 2262, like I currently do in my FX4 and 6, so cost wouldn't be too bad. As far as the bucket and pump solution, I'm afraid I'd be so worried about leaks I'd never get a food night's sleep.The 2262 is a beast and the filter itself is pricey, the media cost almost as much. Since you are talking about seperating it why not buy a 7 gallon bucket + pump and just make your own for like 1/3rd the price?
