You are not getting the concept of HMF, its not used at the bottom.. but a thick foam is used as a wall..
Ok here is the Idea behind the filter.. The image shows the aquarium as seen from the front..

First off, congrats on the new arrival!
The Hamburg Mattenfilter works like a charm. Amazing filtration. It works well in a planted tank too. It is very easy to set up & very easy to maintain. I don't have one right now, but have tried it before.
The thing about this filter is that you NEVER remove or clean the filter. What I mean by 'never' is that it needs to be done only once in a year or even longer. The whole thing about this system is that the filter should not be cleaned. otherwise the whole filter is reset (the nitrogen cycle). And the main USP of this filtration is biological filtration, so resetting it often would defeat the purpose. But most of us redo our tanks in that time span. So we 'never' have to clean the filter. Every now and then, you only vacuum the detritus off of the tank side of the sponge (not the 'sump' side).
But the picture you have shown is an adaptation of the same design. I'm not sure it's a very good adaptation. This system works on slow water flow. If you don't have the filter all the way to the bottom, I don't know how effective it will be. There are better adaptations that you can find with a google search. The corner one seems to be most popular. Also remember, this is not really for large tanks. it is meant for small to medium tanks.
