The Hachtecpet Aquarium Gravel Vacuum Cleaner is a versatile tool that can be used to perform a variety of tasks. With its simple design and easy operation, it’s perfect for use in fish tanks. The air-pressing button has greater suction power than a traditional siphon, making it ideal for removing large amounts of debris quickly. The integrated gravel filter basket ensures that debris is kept out of the water, protecting the fish and shrimp from harm. The long outlet hose is made of high-quality flexible PVC plastic that is resistant to kinking and breaking.
