| One thing to keep in mind w/ Jaubert/ Monaco/ Plenum systems....little rockwork, and light bioload, are required in order to provide a LARGE (reletive to the tank's footprint) surface area. The rock will compract the substrate and reduce the effectiveness of the plenum, otherwise. Juabert also had typically light biloads in order to keep from overwhelming his set up w/ detritus.
