I've got two XP3's on my 55 and then I've got a 2217 that I'm going to put on it later. I love the XP3's (They're my first canisters). They were easy to set up, and definitely worth getting. You can get them for $109 at Drs. Foster and Smith.Dionysus;4001730;4001730 said:Man, those Filstar are priced nice, and the priming isn't as bad as I thought (just lil harder for more being in tight spot) I guess I'm considering three now, the 2028, c-530, or Xp3. I've had good luck with Marinland and Eheim in past, but never tried Rena before.
I'm sure any of the 3 would work well. The only big difference between them seems to be flow, the c-530 rated the highest.
If you're worried about priming them, they come with a little funnel that you use and that makes it really easy.
