That is actually the point of Dr. Jean Jaubert's plenum method.. the levels that are anaerobic are protected with screen so they dont get disturbed and it is used to remove NO3 from the tank like a DSB.. Its a SW technique that I have not heard of being used in FW..

Reversing the flow is what was done just before the UGF's were put out of commision.. they used PH with sponge prefilters that forced water up through the gravel.. for some reason gunk always was in the top 1/4" on these tanks.. I always wondered why it didnt stay closer to the surface..

i just read that its bad to leave those anaerobic pockets.. isn't that why its good to stir up sand substrate?

Yes that is why you would stir sand or gravel for that matter, it is so anaerobic pockets that can become exposed do not do so.. this biological filtration method is for making a place to cultivate and protect the anaerobic bacteria.. It is much like the DSB method wich there is a SW monster island thread devoted to the subject.
This technique isnt new.. there is alot written about the subject.. here is a google search on "Dr. Jean Jaubert Live Sand Biological Filtration plenum" very specific to try to limit the results some..

i guess it would be good if you were really careful and knew what you were doing, but i think id wind up exposing some of the pickets when i do gravel vacs and stuff and i know that realease toxins into the water that are produced by the anaerobic bacteria down there.

no idea, greenmaji but this guy was using it in goldfish tanks and it helped make it easier to collect all the gunk and keep the tanks cleaner. Now I can't find that website...wish I had bookmarked it earlier because I thought about posting it here as "food for thought." Ah well...

By the way.. I am not encouraging everyone to grab there UGF filter plates to build a plenum system.. first off I would suggest that if anyone is thinking about doing this please do alot of research.. It might not be feasible with a FW system for some reason I am not aware of.. I did hear rumors of african cichlid tanks that were being filtered this way but I didnt see any documentation of such endeavors. 8O
