Good water quality is key to a healthy, beautiful aquarium or pond, but the tap water you use often contains disinfectants, such as chlorine and chloramines, to make water safe for drinking. These same disinfectants are highly toxic to aquatic life, and may destroy fish gill tissue and prevent the uptake of oxygen, leading to fish loss. Even low levels of chlorine and chloramines irritate delicate fish tissue. API water treatments and conditioners work quickly to make water conditions superior and safe for your fish, so you can get the most out of fish keeping and easily start or maintain your aquarium or pond. Whether you’re detoxifying ammonia, or treating your fish for disease, API brand has the right treatment for your fish keeping needs.
