I have read the same it seems there is a lot of arguments and it seems to be a touchy subject.I live on forums lately at work trying to do my own research before I ask questions. do you have any suggestions on where I can find 100% aragonite sand..? I kinda want to start with dead sand and make it live w/rocks no real reason besides I would like to say I created something from nothing ha ha
