I have to admit I have learned a lot during this process. #1: if using the silicone peat moss method make sure your Great Stuff is on the smooth side, too many nooks and crannys makes it an even more unenjoyable to do. #2: If you can do the Land mass outside of the tank and drop it is, it has got to be easier than reaching inside the tank to cover things in silicone and peat.
The work continues. The new pictures show the background pretty much done (some touch ups to cover bare spots) and how I added some height to the land mass border with another application of GS so I can layer all the substrate. I am planning on putting down a layer of hydroton, some weed guard, then substrate on that for the plants to root in. How does this sound to everyone?
I need to cover the remaining GS (including the river which I have since siliconed and attempted to put a gravel base on), add substrate, and add some cork in front of the screen in the front. As always, any suggestions are welcome.
