I think its the same. The Fx6 purges or shuts down 2 times in A 24 hour period. It seams that they figured out that was a problem with the Fx5. The moter is also more efficient Uses less energy.. Adjustable outlet tube. Oh yea new impeller designed to last longer. That's nice. And I think that's about it. A great filter.PS. The fx5 boasted 563 US gallons per hr. Don't even get me started about the price!! Would still buy one though. Great filters.
