For the past week or more I have been closely watching the java moss in my planted shrimp and neon tank. All of my java moss has a light carpet of something on the tips of almost every strand. It almost looks like a layer of light gray ash or almost like dryer lint. It's only on the java moss, none of my other plants. I've been wondering if it was some kind of weird algae growing on the moss but today I went to do a trimming of my plants and all I did was lightly brush against the java moss with the scissors and this stuff started coming off and floating all over the tank. I did a quick partial water change to suck up as much of it as I could with the syphon. Does anyone have any idea what this might be? Has anyone experienced the same thing? Again it's only on the java moss and not on any of my other plants.
