I am looking to thin how much rock I have in my tank. I am willing to trade for fish and or corals, and possibly some dry goods. I live in palm springs area, and Do not want to drive to far. How much I am willing to trade depends on what you would be willing to trade. The rock has been in my tank about a month. Its clean, and no hitchhikers that I can see. It was cleaned before putting into tank. The dry rock is from florida, and some has been in my tank for a month as well so It has a good headstart.
