I think so but it was a couple years ago so I don't remember much of it, I should look for it again (got a link handy? I'll look for it too though). I remember Albert was a fairly strong proponent of Zeo and I remember him saying you could add livestock to a tank at 2 weeks on a zeo system. I'd be a little concerned that the bacterial cultures would be all in the zeolites and not the rock especially when starting from dry rock (or at least a 50/50 mixture of dry rock) although I imagine over time a bacterial film should develop over the substrate anyhow..
