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.
