Im afraid that i got some of this stuff in my tank. The beard is on my driftwood, and the staghorn is in my moss. Thankfully it hasn't taken over yet.... The only thing that eats this is SAE's, which get to 6 inches. Correct me if im wrong, but they are a little too big for a 20g tall. Now for the real question: How do i get rid of it without having to destroy my plants or tank?
