Yeah, you might notice I avoid using the B word when talking about this stuff. It's a newer term (at least in this usage) that I believe carries some baggage and was popularized by internet personalities looking to ultimately make money.
On that same note, a lot of your search results will probably be top hits on popular youtube channels and websites trying to sell you stuff. Or total noobs showing a picture of their VERY newly setup "bioactive" enclosure. Getting advice from several experienced keepers can be tough to come by, but forums like this tend to have more time-tested and animal-need-focused methods.
