Help! This 75 lbs of live rock came along with a tank I bought about a month ago. From the beginning I haven't wanted to use it because of the risks associated with using rock from a strangers tank. So I tried to sell it to put the money towards a fresh set of dry rock but without any luck I can't justify buying more rock when I have a bucket full of it sitting in my garage. It has been out of water for about a month drying out in my garage. But I wouldn't want to use it unless its completely clean. But, I also really don't feel comfortable having tubs of muriatic acid laying around the house with family and pets around. I need some ideas!
