I can see how it would make the sand bed more effecient because rather than having 1 surface, you'll have two, with an anerobic core in the middle. (Maybe) It sounds just like another form of fluidized bed filter and it sounds like a lot of work to set one up but I'm interested because I'll be building a new sump soon.
