What's the consensus on this? I've been using D.E. but cellulose fiber looks very attractive due to light weight and "better filtering" but my gut tells me it's not as good and just marketing bs.
Cellulose fiber vs D.E.

I've been using it for a few years now.
Seems to filter as well as DE.
Doesn't leave the white crust where I backwash -- it does break down and disappear into the grass
By the same token, it also starts to break down within the filter. Gets sticky, doesn't backwash well. I usually blast the grids clean with a hose every time. Maybe if I backwashed more frequently...
When the pressure rises 25%, its time to backwash. Not next week when it's more convenient. Now. Once it rises, it just skyrockets and the return flow gets visibly slower.

I've used it in a sand filter to extract iron. Like Richard says, when it starts to block up it does it in a big way.
Is it better at picking up iron? Does it cause problems as it blocks or do you just need to backwash.
I have had a good experience with cellulose and have been using it for about three seasons. I find it filters better than DE, evidenced by very few particles visible by the pool lights at night, but your filter may need more frequent back washing due to this. It is safer to work with since it is organic, but I still would avoid mistakenly inhaling it.
I like it. I use it with my cart filter. Polishes up the water.
