One thing that doesn't seem to ever be addressed with bio active for snakes, when using a CC, is that springs and iso's breed. A lot in some cases. And isopods are hungry. CC's work great with frogs or geckos because they will also eat them keeping the population in check somewhat. Especially springtails. Snakes obviously won't eat then. CC's will need something to eat. The snakes waste won't do it. The video I've seen on YouTube where people put in these large size iso's is ridiculous. Im a definite newbe with snakes but I dont think bio active is right for them
