I used the Mags, for awhile, but I upgraded to a larger tank and needed more flow so I bought what I could afford. I got a Rio 3100. Then I upgraded again to my 120 gal. I have now and still used the Rio 3100 (900 gph). That quit working after 2 1/2 years and needed a pump fast. I called Shark Reef and got a Rio 17 HF (1190 gph), that's all he had, unless I wanted to go smaller. I have been pretty happy with it, it is quiet and pumps water great and it was only $80.00.
