[Chase31]

well thought i might as well give a small update, getting rock sometime next week (calling and arranging on Monday) the sand is starting to get a red layer almost on it? not sure what this is almost looks like very tiny amount of rusting but i know its not, lots of critters on this rock, all very very small, some tube worms that poke their little fans out witch is cool, are these a form of feather dusters?
