Very nice progress...
as always your tank looks freaking amazing.
Don't hold your breath.
Marc stay strong I really think the open aquascape is better for the animals and looks so much more natural than a wall of rock. I am surprised you haven't closed in the front of the tank/sump, if you did wouldn't the house have less noise? May be its my tank but the amount of noise in the living room is bothersome. Thanks for finding the time to keep us all up dated.
