Yeah the new multistages from marineland look promising. I used the mag 350's and they did a fine job for me. I used to have an old fluval 303 and it licked *%#^%# but i got a 304 and it was suprisingly better. After that I switched over to Eheim. I think I am now going to go and get me a Fluval 405 or the New c-360 Multistage from Marineland. I wonder why there isn't much talk about them any where I go or on any forums?
Once I go larger than a 180 AGA there's no other choice, I feel.
