I like it! I like it a lot! I think you need to kick down for some more moss for that grid though, hehheh. The setups I have seen online have enough moss initially to wind thinly across the grid before they put it in the tank.
I have actually been toying with the idea of a moss wall as well, but I would have to take down one of my tanks and set it back up again. That, plus the expense of buying enough moss to fill a grid makes me drag my feet.
Two 1 GA desktops, a 5 gallon, a 2.5 gallon, a 10 gallon, a 20 gallon, a 25 gallon, and two 75 gallon tanks, all planted.
I am an expert on algae, so ask me if you have questions. I know how to grow it, just not how to get rid of it.
