I wonder about compromise here. I have tried "aquarium" #2, 3, 4 of
gravel (these are the commercial size markings on the bags, #2 is
about 2mm).
This sounds more like the sand that is used in concrete, I have used
that too but it packed on me a lot. Maybe we could get a bunch of
different sizes and try them? Or????
