Hi All - I am rehabbing a JBJ 30gallon AIO and I wanted to know if there is any particular reason, other than design, that there is a baffle at the bottom of each chamber. It seems like a waste of space. That's space, if easily accessible, could be used for additional bio media. Before I remove it, please share your thoughts. Also - why the extra pane of glass on the left and right. Seems unnecessary...especially if I use inTank media baskets, which do not hang.
