I've had a planted tank now for about a year and the plants were growing great. I had an enormous amazon sword which suddenly has black inky looking spots on it. It's not hairy, more spotty. It's also on my Java Fern. I have to clip off leaves quicker than it can regrow them and I'm not sure what do. Appreciate any insights you guys have.
