I have long been trying to get a decent moss wall started, but keeping it neat and preventing the moss from escaping and spreading throughout the tank has proved to be impossible. The moss wall was in a tank for about 6 months, and never proved very successful. I tried making a wall from Susswassertang, but using double walled netting, the Susswassertang tended to grow between the 2 platic walls, resulting in the wall bulging. The third attempt is a single piece of plastic mesh, with the Susswassertang glued to the mesh, and the mesh reinforced with plastic file binders. Hopefully in a month or so I will have a solid wall of Susswassertang. I am using it in a grow-out tank that has CPD fry, Assassin Snails and feeder shrimp. Hopefully this will give me the look that I want.
