Yeah, I've got a 350 pro on my 37 gallon tank. It stay spotless and only needs a little maintainence from time to time. It's been going for 4 years now without a hitch
I bought our mag for about 80 dollars, do those 120-200 dollar filters do anything that a mag cant, i can put whatever media i want in it, has high flow, simple to operate, i haven't seen any real tests on filters to compare them, but i just don't see how spending more is going to filter so much better thats its worth it.....
