I can certainly throw in my 2 cents regarding zeosand as opposed to DE/Sand media. I run several indoor facilities and was sold on zeosand as being able to help lower our CC levels and to be honest I never noticed so much as .01 drop in CCs for the 5 years we've been using the zeosand.
What I do notice though is that the zeosand tends to channel in the filter meaning it creates a pathway through the media from the top of filter down where there's no media, it will also clump together. I regularly have to remove tops of filters and stir the media while in backwash mode, very messy. Obviously it's no-where near as much maintenance as DE filters but, no matter what's being said on here zeosand absolutely will not filter as well as DE either! And I'll stand by that statement.
Nothing filters like DE.
DE filters were an absolute nightmare to maintain in our commercial facilities as you could imagine but the pools with DE filters were by far clearer and more polished than any other filter/media I've used and I've used them all.
Our most recent facility was built with filters using just plain old sand media. We decided to just go back to the basics....oh that and to install a shiny new $20K UV system........what Chloramines? :-D
