Review: This works- happy, healthy fish - Excellent additive; use this each time I do a water change (add it to the pitcher I use to refill and pour it into the tank behind the filter media.) Have never had issues with my fish when using this, unlike some other additives I have used in the past. It is concentrated, so lasted about 3 months with weekly 10-25% water changes in a 20 gallon high tank. Review: A quality product. - The API AQUA ESSENTIAL water conditioner is amazing! It works really well and the fish love it as well. I’ll surely purchase it again. ## Features - Contains one (1) API AQUA ESSENTIAL Water Conditioner 16 ounce bottle; treats up to 4,730 U.S. Gallons - WORKS INSTANTLY: Highly concentrated aquarium treatment works instantly to remove harmful chemicals, making tap water safe for fish in freshwater, saltwater and planted aquariums; Reduces the risk of fish loss when starting or maintaining a fish tank - DECHLORINATOR: Removes chlorine, chloramines, heavy metals which are found in tap water and can cause gill and tissue damage, breathing difficulty, stress and fish death - AMMONIA REMOVER: Removes the toxic ammonia continually released by fish through their gills, urine and solid waste.
