  • Publication number: 20210180702
    Abstract: An attachable flow rate controlling device comprising a flow rate control unit and a fastener is disclosed. The flow rate control unit comprises a chamber and an adjustable valve. The adjustable valve is configured to control the rate of water flow by converting the adjustable valve to turn on/off, so that a fish keeper is able to control the rate of water flow from an aquarium. Additionally, the flow rate control unit is fixed securely or pasted around an opening of a bucket or on a flat surface by the fastener. As such, the fish keeper can change the water in the aquarium and control the flow rate of the water from the aquarium. The attachable flow rate controlling device is controlled by rotating the adjustable valve hence enabling the fish keeper to use the attachable flow rate controlling device without repeatedly refilling the siphon hose with water.
