BornFeel Aquarium Air Pump Splitter 13 in 1 Set 4-Way Air Flow Control Lever Valve & 4 Non-Return Check Valves & 8 Suction Cups for Fish Tank Airline Air Tube Hose

The BornFeel Aquarium Air Pump Splitter 13 in 1 Set provides an easy solution for those who want to control the airflow in their aquarium or hydroponics system. It includes a 4-way air flow control lever valve, 4 non-return check valves, and 8 suction cups, making it versatile and convenient to use. It can be used for different purposes, such as air adjustment, drip acclimation, and oxygen supply systems. The set is made of plastic, not stainless steel, as verified by a customer in the Q&A section. The size of the air pump needed will depend on how many connections, how long the hose line is, and how deep the unit is underwater. The splitter can also be used backward, as one customer suggested, with tube parts that can connect the outlets of pumps into one hose. However, some reviewers have reported that the check valves included in the set are of poor quality and do not work correctly. Overall, the BornFeel Aquarium Air Pump Splitter 13 in 1 Set is a useful tool for those who want to control the airflow in their aquarium or hydroponics system without having to purchase multiple air pumps.
