I really, really wanted to use Live Aquaria salt. Everyone that I know and trust in the hobby speaks so highly of it and the price is typically pretty dang good. However, I had some strange negative results and ended up giving away what I had. It could have been any number of issues and the salt use was coincidental BUT every time I did a water change with LA salt, my stylophora's would turn white. Just the purple stylos. So strange that I can't believe it was just the salt but I tested it many time because I had 3 boxes of the stuff and it happened over and over again.
