Just wanted to add in some more stuff that I've been reading. It seems that people with bioactive setups tend to have alot less problems with mites. Been keeping up with the facebook group on it for a little bit now. Some people report the predatory mites as wiping out their cleanup crews although some with very healthy populations have actually gotten the predatory mites to balance with the springtail population and live there permanently. They apparently can predate on the young of springtails, but the springtails can out reproduce them as long as they are well established it seems. Springtails aren't their preferred food though (much faster than mites) and any time any other mite tries to move in the predatory ones quickly mop up the problem. Also some evidence suggests the springtails actually compete with the larval stages of snake mites for food and can effectively starve them in the right conditions. Also some anecdotal stuff about them eating the mite eggs.

This in addition to the benefits to shedding is really making me want to go bioactive here soon (probably when my new girls are out off QT....I might go ahead and start working on building my substrate sooner than that in a bin.
