NJDF, I am force to clean the spray bars, they clog it I don't. I was just making the point that I never have to clean a spray bar on the 170.
ZZYZX, the media compartment is without a doubt larger. As far as tanks the filters are on I would say it is similar. The 280 is on a 29 while the 330 and one 170 are on a 55 and the other 170s are on 20's. I just like that I don't have to constantly clean a spray bar in the penguins, just rinse the filter every week. They also prime easier. Just my observations, I think whatever filter someone choose is their choice. Besides I'm on an AC kick now, I love them.
