WORKS INSTANTLY: Highly concentrated aquarium treatment works instantly to remove harmful chemicals, making tap water safe for fish in freshwater and saltwater 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 DETOXIFIER: Detoxify ammonia continually released by fish through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia. Small amounts of ammonia stress fish; large amounts of ammonia will kill fish NITRITES AND NITRATES REMOVER: Produced by fish waste and uneaten fish food, nitrites inhibit respiration and suppress the immune system at low levels, while high levels cause suffocation; Nitrates can be harmful to fish and lead to algae growth AQUA ESSENTIAL water conditioner is a highly concentrated all-in-one water conditioner that instantly makes tap water safe for fish by removing chlorine, chloramine and detoxifies heavy metals commonly found in tap water. AQUA ESSENTIAL water conditioner instantly removes toxic ammonia, nitrate and nitrite levels in freshwater, saltwater and planted aquariums. Toxic ammonia continually released by fish through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia. Small amounts of ammonia stress fish; large amounts of ammonia will kill fish. This unique formula binds with ammonia, nitrite, and nitrate rendering them non-toxic and allowing the biofilter to more efficiently remove them. Use at start-up and whenever adding or changing water or when tested levels of ammonia, nitrates or nitrite are high. When adding, transporting or quarantining fish, we recommend using API STRESS COAT water conditioner which is ideal for use with AQUA ESSENTIAL water conditioner. Directions Using dosing cap on bottle, add 5 ml. per 50 gallons of aquarium water to treat tap water. Add 5 ml. per 10 gallons of aquarium water to remove ammonia, nitrite, and nitrate. We advise you to wait 24 hours after dosing then do a water change. If you dose within that 24 hour period there is no danger to the animals/plants in your aquarium. A follow-up water change is always beneficial to an aquatic system.
