Tap Water Safe removes chlorine and other halogens, chloramine and heavy metals found in tap water, which are toxic to fish. Tap Water Safe also contains a special protective coating that reduces stress caused by transportation of fish.
Use when filling a new aquarium and anytime when adding fresh tap water i.e. during a water change. Also use when moving fish from one place to another: simply add to the transport bags.
