DaPrawf Posted August 7, 2022 Share Posted August 7, 2022 My 29 gallon tank is about a month old. Before I put driftwood in the tank I boiled the pieces for about an hour. When the driftwood went in the tank if nevertheless developed a sort of white film, which I assumed was the fungus I had read about. When I did a big water change, some of the wood was exposed to the air. After that the film turned gray and got steadily darker. Could it be black beard algae? So far it is only on the drift wood. My nerite snails have ignored it. I'm going to be adding some cherry shrimp to the tank next week. Would they go after it? Or should I undo the aqua scape, pull out the driftwood and clean it manually? Thanks. 1 Link to comment Share on other sites More sharing options...
Patrick_G Posted August 7, 2022 Share Posted August 7, 2022 That looks like biofilm. It’s easy to remove with a toothbrush and it’ll eventually go away on it’s own. Link to comment Share on other sites More sharing options...
