My impression is that the Eheim 2227 and 2229 are canister filters that
gave
some of the benefits of sump, or bio wheel filters.

These seem like a decent compromise from the optimum sump set-ups. It would
really simplify my life if I could set-up with one of these filters with a
good conscience.

I need to know specifically if the 2227 or 2229 are acceptable ways to go to
filter f a 65 Gallon Marine tank,
and if the 2229 is CLEARLY a better way to go.

I also would appreciate suggestions of different ways to go---I am basically
looking for a clean cannister-like approach. I was looking into the Tunze
reefpack 500---but uts a bit out of my budget. Would that simply BLOW-AWAY
the Eheims that I am looking at?

thanks SO much.
