That's the crap I was referring to...and the bacteria won't be gone for long. Bark just harbors bad stuff...the rock is unnecessary, the tree is unnecessary, the half log, in addition to harboring yet more bad stuff, will probably be outgrown soon...Why fight it? You'll eventually get tired of fooling with all that stuff and struggling to keep humidity up and go to tubs or a rack setup...especially when you look in the tank and don't see anything but tank "decorations"...balls will usually be in their hides....just a matter of time. I guarantee most folks here went through the same thing...me included...it sucked...I got tired of it...moved to racks and have never looked back...good luck either way. I sincerely hope it works out better next time.
