ok so I'm thinking about starting up a tank again I tore down my last tank when my now six year old daughter was born I just didn't have the time for it. the question I have is I kept all the live/base rock but it was left outside is this something that I could use again if it were cleaned and cooked or would it be better just to go buy some again? I'm just wondering because it has sat outside for years but then I think to myself some of the base rock people buy im sure has sat out somewhere. if I can still use it what would be a good way of getting it ready? thanks for the advice
