Java moss

Funny, I was just about to post some questions about java moss too, so I'll do so here instead of in a new thread. How does one go about siphoning the gravel underneath java moss without destroying/disrupting it? How much light does it need? (best I can find is "low" which really doesn't qualify anything... I've only got 0.6 wpg on my tank right now (the lights that came with it) so I don't know if they're bright enough) What are the co2 requirements for it? (can't find anything at all about it) I like the natural look it gives things, and I want to give it a shot... but I want to be semi-informed about my decision before going ahead and doing it.
 
Java Moss looks a lot nicer when its atached to soemthing. For whatever reason it just developes more fully.

Look at a bunch of Amano pictures to see how moss can be used to make driftwood look much more natural.
 
I've been told when attaching plants you simply need to use regular sewing thread (and that it will desolve away after time).

I don't know that I'd use fishing line, but whatever works I suppose.
