I have run the magnum 350 on my small tank (30 gal
) and a couple on a 125 gallon. They have been great, very very simple to install, possible get the quick connects just to make it a little easier to clean! They have a very simple design, the polisher removes HUGE amounts of gunk from the water column and they are reliable and silent!
However, as Steve points out, they are expensive and some say debateably unecessary piece of equipment when you use a high quality skimmer with a decent ratio of lr
to water. --- I guess what i am saying is this; IF you are wanting to get a canister, then only go with the Magnums!
