Long time pool owner (egad, has it really been 25 years?), first time poster.
It's time to replace the original (circa 1968) American Titan DE filter and I'm wondering about bump vs grid technology. I like the idea of being able to reuse the DE media a few times, but not if it comes at the expense of more frequent filter maintenance. We get a good deal of dust, both very fine and fairly coarse (wind blows from the desert), and my wife is fanatic about sparkling clear water. I'd also like a filter that can give at least 15-20 years of service (with occasional tube/grid changes etc) so I don't ever have to replace it again.
In-ground pool + spa; I forget the size offhand but the old filter was 36 sq ft (I think). I'll probably go a bit larger this time in hopes of less frequent service. I'm near Los Angeles if that makes any difference (medium hot, medium dry climate).
Opinions, experiences, brickbats all cheerfully accepted
