These are all new photos!
Some are still from individual areas, but I have tried to include larger (all most) full shots.
I allowed some of the photos to include viewing the depth of the substrate.
It's a bottom layer of living clay from one of my best ponds, a layer of rinsed mulm and organisms from the pond and a deep layer of rinsed river sand in collected from the Rogue River here in Oregon!
Parts of the house have been moved since this was placed(six, or so, years ago) and I can't get to a proper angle for a really good head on photo anymore.
Here's what I was able to come up with.
I really, really tried to cut down on the above water glare and even turned out some of the lights, but there is still quite a bit of it.
