I'm getting a Pentair Quad DE 80. I'm replacing my old, but still in great condition Stainless Steel 36 sq ft DE filter, that just can't keep up with the amount of extremely fine silt the dogs constantly drag in (plus the wind). It filters it well enough, although I think the Quad will do a better job. The main reason for replacing is that I now have to backwash my old filter at least twice a week, sometimes a third time (few weeks ago did the pre-soak and acid soak of grids in addition to replacing four grids that were not torn but plastic getting weak). We've always had dogs swimming but now we have three active large and GIANT puppies who have multiplied, exponentially, the amount of silt going in to pool. I've switched to cellulose, not sure if I'm going to continue, because of the extreme amounts of DE I've been putting into the environment. We already have enough silt flying around and all my runoff eventually makes it to protected habitats and state park lake.
I have the Quad 80 ordered but can make a change if necessary as I am picking it up locally, at a warehouse.
I really like the idea of being able to take the top off to rinse out filter media.
Are you really, really happy with your Quad?
Do you have experience with other DE filters with which to compare?
Discovered any cons?
Have you tried using cellulose as filter media for your Quad instead of DE, or have some info about that?
