I few months ago I bought a amount of java moss at my local lfs, I got it on
bargin since it was the last one in their tank, it was DARK green and in bad
shape. I have since then trimmed out all the brown dead material and wrapped
around a little gargoyal , I have not seen any new growth from it in a 20
gallon planted tank with 2 watts/gal, CO2 infused, there are no imballances in
the water so I know its not a problem there. Is there anything I could do to
stimulate the growth so as to see a reason to have it?

any help would be welcomed
thanks in advance
