I started and aquarium a few months ago with driftwood. I tied some java moss to the wood and early on saw some great growth. Then this blue/grey fuzz started to appear on the wood. Soon after it started showing up on the moss. Now I've removed almost all my all the moss in an effort to get rid of it. The moss left looks like is has this blueish spider web coating every strand. I do a 50% water change once a week. Yesterday I got an oto cat and some small snails, not sure what kind. They havn't made any kind of dent yet. From what I've researched there doesn't seem to be any one good answer, what do you all think?
