so i want to do a riccia rug growth wont be a prob but i wanted to know what kind of mesh to use i have heard stainless steel, then a certain kind of stainless steel, then heard don't use it and use some other mesh... help would be great thanks!!!!
I personally prefer using several flat rocks with hairnets to hold down the riccia. This way when it's time to trim you can remove the rocks and trim the ricca and then place back in the tank.
