hi i have another background question. does any one think or know how easy/hard it would be to buy loads of lets say christmas moss and stiff moss mesh (enough to cover 40" by 24") and grow the moss in to the mesh then once the moss it well attached on to the mesh stand it up at the back of the aquarium? also would i need to put in c02 to sustain that ammount of greenery or can moss grow well without?
