I've been using this regularly in my freshwater pools since the fall of 1999 with no crashes or problems. I recommend it for the health and safety of your fish in tap water. Use it regularly to remove chlorine from your tank when you first fill your tank, when you do a water change, and when you add fish to your tanks. Highly recommended.
