I had a java fern in my 10 gallon and it is still doing good but it has made a lot of little plantlets. They are all doing well but they're not growing. I have been adding CO2
booster liquid into my 40 gallon, in which I moved the java fern from, and the fern seems to be dying as I see more dying leaves on it. What type of CO2
additive do I need to keep the ferns growing and healthy?
