Tetra® products are dedicated to helping seasoned hobbyists and beginners alike enjoy a successful, life-long experience. Tetra products build fish-, reptile- and pond-keeping confidence, one innovation at a time. Our complete line of Tetra reptile products makes keeping reptiles such as turtles, newts and frogs, simpler and more enjoyable. Tetra® ReptoClean® solution contains a concentrate of beneficial bacteria that detoxify water and accelerate the breakdown of organic matter such as food waste, reptile excrement and dead plant parts. Help create a clean and healthy environment for your reptiles by applying Tetra ReptoClean solution monthly to water to reduce sludge buildup, detoxify the water, provide a healthy biological balance to the water and reduce the load on the filter. This will also help extend your cleaning intervals. A 250 mL bottle of Tetra ReptoClean treats 250 gallons of water. Apply monthly using 10 mL per 10 gallons of water.
