Hi guys i need help. Bought 2 balls of Java moss yesterday from a fish farm, all looked green and healthy and today when i just found some top of the moss turned into white color or brown for no reason. here are some pictures of my java moss, I'm sorry about the pic quality in advance. I've never tried to dose CO2 or any kind of nutrients to the tank before. Also i'm using nature daylight instead based on my low-tech tank. I'm not sure what is the problem caused since i'm new with this, Any help would be much appreciated, thanks
