Nice video. I did a moss wall myself. I've just one comment to add.
I used clear suction cups and for some reason they turned white. The white cups up against my black background looked awful until the moss covered them, which took quite awhile. I used the larger squared mesh in black.
I used Christmas Tree moss which, IMO, is a slow grower. Of course the smallest fish in my tank managed to get stuck behind the wall and the boyfriend destroyed the wall getting the fish out. I was on vacation at the time and if I was home I'm not sure I would have destroyed the wall. Before I left on vacation the moss wall was looking really nice and I was looking forward to posting pics when I returned.
Anyway, long story short, I took the entire wall out and will be trying again next week, this time with black suction cups.
Looking forward to seeing pics of your tank once the wall has a chance to grow.
