Hey everyone, im pretty new to planted tanks and am cycling my first tank. I have mopani wood in there with peacock moss tied on with cotton string. It has 2 zebra danios in it and has only been cycling for 3 days. But the wood is starting to get some opaque white stuff on the top of it and it looks like it may be on the moss as well. What is this stuff? Will it go away by its self? Will it kill the moss (the moss definatly has not rooted.yet as its only been on for 3 days)? What should I do? Thanks!
