I just got some narrow leaf java fern, java moss, and anubias from a LFS (FREE moss, nice people!) And I'm about to sit them in a container of untreated water since I learned that it's good for killing off unwanted creatures.
What exactly IS a narrow leaf java fern? What ever it is, it's WAAAAAAY taller than an ordinary one, and I bought it to help baffle my filter. And this untreated water thingy works, right?
