Thanks,
It's just temporary for now. Once I am done, you will not see the excess rod sticking out of the tank. Not to mention, there will be more caves and overhangs as well. My reason for doing this is that it allows more flow behind the rock than a rock wall does. This tank is going to be very open; I have no doubts that some of the rock will end up in the sump.
