I finished my viv, for the most part. I'm not sure what's up with the water fall... i tested and tested and tested throughout the build to make sure the water would end up where i want it to, but now some of the waters trickling down another route and pretty much saturated a area of the substrate ... Might have to remove some dirt and replace with some stones. In about a week from now ill introduce a colony of springtails and some isopods then after a few more weeks-the hoppers will be kicking it oh-natural.
