DO NOT USE FILTER CLEANER ON THIS FILTER! It does not clean and will lead to plugging it up, It is disposable and has a life expectancy of 3-6 months. Can use UCF-488 (6540-488) Filter to take the place of the two filter system. It would give you a single large filter with a divided wall for the circulation pump system that is cleanable. c-8380 Unicel Part Number.
