This mold/fungus has grown in all the of sphagnum moss in my tank, it started in the moss surrounding the plants and now is in the moss in the plant pots. It seems to be killing the moss. Has anyone seen this kind of thing before? Can it be treated or must all the moss be replaced and plants re-potted? Most importantly will it hurt my plants? (It has been there about 4/5 days and they are unharmed) Thanks for any advice, here are some pictures:
