The java fern is in the flora max so I will pull it up and attach it to a small rock. Thanks for a heads up. Anything in particular I should tie it down with? Fishing string? And if need be I will track down some soil and pull the tank up and start over. I can't find the miracle grow organic choice potting mix but I can find the organic choice garden soil. Is there a difference?thanks for all the help by the way.
