In both HOBs I have there is fluval or eheim biomedia instead of the stuff (sponges or cartridges) that came with the hob. In top of the media there is a small square of sponge or pad (don't remember), in top of that moss and in top of the moss plants.
In one of the hob the moss goes all the way down to the substrate of the tank and the plants too.
When I clean the filter I just pull the plants and moss that is attached to that pad or sponge and fold back into the tank, go clean it, put it back in the tank and then unfold/ place the pad again in the same position, there is very little root growth into the media.
A heavily planted shrimp tank is possible!
