Sorry, im english.
right, in the UK i cant find a clip on external power filter anywhere.
So i got to wondering, i have a "Fluval 304 MSF Canister Filter" (a differant design to the one on sale in the US apparently, but thats what it says on the box) and it says, "suitable for 55 - 70 gal"
however, what makes them so much more expensive then the 330 Penguin Bio-Wheel Filter?
and what are the benefits of each type?
any help would be great
cheers
Craig
