I've been setting up and getting ready for an octo for a while now. And one thing that I notice is in most of the tank setups I see, there is a lot of PVC and other things but very little live rock. I'm an experienced aquarist and the rule has always been equal gallon to pounds of rock ratio. With the high ammonia output of the little guys wouldn't it make sense to use a natural way to take care of the ammonia as well as filtration?
