Thanks for the complements. I admit I was nervous when I plugged the filters in. I didn't know what kind of reaction may occur running a Renna and an Eheim on the same tank
The wood in the background was collected from the Niagara River and attached to a frame I made out of 3/4" PVC. The wood was still floating when I started setting the tank up so I filled the PVC with old aquarium gravel to give the frame some weight. Once cemented together the frame was sanded with 100 grit sand paper and spray painted with a paint made to adhere to plastics by American Tradition.
In the initial photo I had black craft mesh tied to the frame with the intention of tying moss and ferns to it. Good idea but a PITA in practice. Long story short I removed the mesh and went with a different method that I have used in the past. I cut the black craft mesh into strips, snip out a couple squares and push in two or three suction cups, tie some java fern to the mesh with black thread and attach it to the wall of the tank. I think of it as modular java fern. It has worked well in the past and in this case gives the tank some added depth.
