What a change over and still in the process, but has anyone else found that less is actually more? I had so much rock, which is slowly being removed-instead of having 3-4 rock deep and 3-4 rock high, I find I am scaling back-way back 1-2 deep and 1-2 high...things become so much more stable, to say nothing to the ease of cleaning and maintaining. Is anyone else going down this road?
