I had received 5 medium size lava rocks with riccia tied down to them, and it's been alot of work and mess. I don't know if it was on this board or another, but someone unraveled and used a shower sponge, which is mesh and unraveles into a tube. Well, I just finished wrapping these around the stones, and it looks like a great method. I also learned that using a python, attached to your faucet in suck mode, is really good for cleaning out all the plant bits floating on the surface. Two good finds in one day, amking this tank look much more managable. Now, if I could only find the green version of the barclaya longifolia that was recommended as a good discus planted tank centerpiece.
