I have a ten gallon newt tank and its filled with plants. My wisteria and red ludwigia are doing great, and so is my other plants. I have 28 watts or a 90 watt equivalent. My java moss is attached to my drift wood by string and it is growing painfully slow. Its not even attaching itself to the driftwood! I just wanna remove that string already. How do I make my java moss grow faster?
