So a long time ago my wife had purchased the wrong substrate for her fish tank. It turned out to be live sand for saltwater aquariums. I said put it aside maybe I will some day have my own fish tank and that will help. Well years and years went by and sombody had mentioned the tank size for our Boa seemed small. So we looked at upgrading his tank to a larger size. Once we did that we suddenly had a 55 gallon tank laying around and suddenly this bag of sand turned up again. So with a little arm twisting i started looking into it.
