Biological Turtle Habitat Cleaner - Cleans aquatic turtle habitats and gravel - Reduces and controls odors - Quickly reduces organic waste Exo Terra Turtle Cleaner is a 100% biological turtle habitat cleaner. When used weekly, it helps control odors and break down solid organic waste. Exo Terra Turtle Cleaner aids in eliminating organic waste in turtle habitats. This powerful biological formula efficiently reduces solid waste and food remnants, which are a natural result of turtle feeding. Exo Terra Turtle Cleaner improves filtration efficiency and is effective in odor control. The natural byproduct of Exo Terra Turtle Cleaner serves as a food source for beneficial bacteria. Turtles produce organic waste in various ways; as they grow, they constantly shed parts of their shell and skin. During feeding, turtles tear food with their claws, producing large amounts of waste. This negatively impacts filters and can easily exceed the capacity of the existing biological flora in their habitat unless Exo Terra Turtle Cleaner is used. Exo Terra Turtle Cleaner will establish the appropriate beneficial biological flora to ensure significant breakdown of organic waste when used at the recommended weekly dosage. Usage Instructions: Shake well before use. 5 ml per 38 liters / 10 US gallons of water. Use this dosage at initial setup and as a weekly treatment. Exo Terra Turtle Cleaner is essential for providing clean water conditions for your turtles, but it is also important to use a water conditioner to detoxify tap water before using it for your pet turtles. Exo Terra Aquatize (PT1979) effectively removes chlorates and chloramines, neutralizes heavy metals, and adds essential oils to enhance the shedding process and maintain shell and skin health in optimal condition.
