Aquascape Pond Detoxifier Professional Grade makes tap water safe for fish and plants, allowing you to spend more time enjoying your fish and less time worrying about them. Pond Detoxifier removes and detoxifies chlorine, neutralizes ammonia, and detoxifies and chelates copper and heavy metals that can harm pond fish and aquatic plants. Each bottle is 25% more concentrated than the consumer equivalent, making it the ideal choice for discriminating pond professionals. Tap water, including well water, often contains chlorine, chloramines, and heavy metals and it is important to eliminate any toxins in your pond water to ensure the health of your ecosystem. Pond Detoxifier also allows some metals, such as iron, to be used as a fertilizer, helping your plants to thrive. The included measuring cup and dosage guide make application simple and easy. One bottle measures 1 gallon and treats 96,000 gallons of water.
