Good water quality is the key to a healthy, beautiful aquarium/vivarium. Tap water contains chemicals, such as chlorine and chloramines, which make water safe for drinking, but are highly toxic to aquatic life. Tap water must be treated before adding aquatic turtles, newts, or aquatic frogs to make sure they remain healthy. API TURTLE WATER CONDITIONER makes tap water safe by removing chlorine and chloramines and detoxifying heavy metals. Use when setting up an aquarium or vivarium, and when adding or changing water. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium.
