I have heard rumors of different types of playsand that is safe for your tanks. I have not been able to find any white Kolorscape sand or any old castle. I found some white sand called by Pavestone that is very white. I was curious if anyone has ever used it or heard of it being used? What is the deal with the vinegar test? Is it supposed to fiz or not? I havent tested mine yet but will later.
