We have (2) Ultima II 6K's. Since we use them for mechanical filtration (before J-mat biofiltration chambers), I backwash and rinse them (using the factory instructions, above) daily.

If we were using them for polishing after the bio filtration, I'm sure that once-a-week cleaning would be sufficient.

are you talking about me? i know you said my filter is in reverse order i backwash every week for about 20 mins and then rinse for about 3 mins to drain enough water out for my weekly W/C.
