Thanks man,and I don't even use CO2, just Florish Excel twice a week,In my big planted tank I am not even using substrate it a very fine black sand, in pics 2-3&4.And like Jake said you can use fishing line to secure it to what ever you want, I have done this a lot in my tanks, and it works great but make sure its like 4-6lbs test so its thin and you won't be able to see it that much.I only use the mesh when I take a cutting off another plant and want to start a foreground or wall,What I do is figure out what size mesh you want to use, Then double the length so that you can fold it length wise, once you have done that spread the plant that you are using in between the mesh, Once you have done that I just use the fishing line to secure it together,And in no time the plant will work its way through the mesh pretty soon you will have a hole pad full,But make sure you close all the little gaps with fishing line, because if you have little fish they will find a way to get stuck in it.Good Luck and Hope it works out for you,
