you can get is shipped to you for like 3-4$ per pound, sometimes more...it takes a couple weeks to cure...either stick it in your tank and let it cycle, if there is nothing else in the tank, otherwise stick it in a rubbermaid container with a pump and heater, and let it cure... I see your planning a 10 gallon, ordering online isnt going to be practical for you...justbuy it at your lfs, that way you know what rock shapes you want/need, and you can get them.
