My personal opinion is that sulfur reactors work fine - but - they need to be watched carefully. Let them go partially stagnant for a couple of hours and your in for big trouble. Now, that's probably not a problem for most diligent people who keep a sharp watch out for all parts of their systems. Me, I'm likely to forget to check on a part here or a part there every one in a while. So I stick with things that tend to be fail safe.
Following the many threads that currently exist on RC (and elsewhere) about the bio-pellets, you definitely get the idea that there a things we don't yet know about what kind of environment tends to make the pellets most efficient. Some users feel that they are the bees knees (I'm allowed to say that, being old as dirt). Others don't even seem to be able to get them to work. I think it's too early to tell where the whole thing is going. I will say, I definitely don't think the whole thing is a fantasy. There is way too much anecdotal evidence pointing in the direction of success.
Having said all that, mine are working. You can see that the beads in my reactor are getting smaller. Something is eating them away...
I've been spending so much time with developing my site that I haven't been visiting the boards as much as I'd like.
