im going to be setting up a long 20 gal tank and was wondering what would be a better filter to get. i've ben told that the penguin bio filters work pretty good, but no and just wondering which one to get. I was thinking of either the 170 which is 170 gph or the 330 which is 330 gph. or any other suggestions you might have,
-Thanks
