The DE does the filtering, the tubes give it something to hold onto, and the bump handle shakes the coating loose and redistributes it. Once a tube splits or the fabric goes slack, water takes the easy path through the gap and dirt goes back to the pool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBuying in fives\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTubes in a nest see the same water and the same bump cycles, so they tend to fail in groups rather than one at a time.
