^uhhh...which one should i talk good about? Magnum 350...never tried one but I've read about about them being really good water polishers. Marineland C-360...also never tried one. I was interested in buying one because I liked the design and engineering going into it (basket gaskets and the attempt to eliminate bypass, as well as including bioballs).
Eheim...Here's one I actually have. I have a 2215. When I started moving stuff over from my old tank to the new one, I setup the 2215 to start building up bacteria and cleaning up the water from the used substrate. I started out with really cloudy water the night before and woke up to clear water. I was amazed by the filtration. I am also impressed at how much flow it has, even when dirty.
Fluval 205: Not a bad filter, but not perfect either. Wished they used standard hoses instead of the ribbed one but I see their intentions. I like the aquastop valve, except when it weeps a little water when I adjust the flowrate. It's my first canister so I'm a fan of it. I just like my Eheim more now.
