... experimenting w/ my new tank. trying to start w/ primarily "dead" rock (old LR from other's tanks) and build up the bioload by seeding w/ some nice, colorful LR and a bit of sand from established systems, perhaps some GARF "grunge" as well. Size/shape are unimportant. I live in SF, so only interested in those less than 1-1.5 hrs from the city. Thanks in advance.
