Easy-to-use gravel vacuum with self-priming and continuously adjustable water flow. Includes a hose and other useful accessories such as a hose holder and suction restrictor. The self-priming function allows you to quickly start the gravel vacuum's water flow by pressing a button on the suction pump. The adjustable water flow allows you to adapt the suction strength to the needs and size of your aquarium. The robust gravel vacuum is durable and made of high-quality materials. It is made entirely of water-neutral plastic and can therefore be used safely in saltwater aquariums. Includes 2 m of hose (12/16 mm) that extends up to a maximum of 50 cm.
