Ok, so I neglected to read on before I sent my reply.  Can you tell that I'm
just catching up on my digests after a busy week?  This is the stargrass
problem that I was talking about, which I keep in check by keeping it
clipped low.  I gues the tips are just more resilient.  And no, I don't add
CO2.  At least, I don't hook up my soda bottle with any consistency.
