The Abyzz Flow Pump Magnetic Holder is a versatile mounting solution designed to securely attach the Abyzz AFC150 Flow Pump to aquarium glass. This magnetic holder ensures that the pump remains stable and in place, preventing any movement or noise that could disturb marine life within your saltwater reef environment. The holder includes two magnetic disks with rubber protectors—one for the back of the pump and one for the outside of the tank—to ensure a safe and non-slip grip on glass surfaces up to 1 inch thick. Additionally, it comes equipped with titanium screws for durability and ease of installation.
