Multi Flow 1 12/16 + 4/6 Hobby

The Multi Flow 2-way directional control valve (bypass) is perfect for supplying spawning tanks, such as Nido 4 or Nido 5, fresh, high-oxygen and filtered water. For this purpose one simply connects the Multi-Flow to the existing hoses (12/16 mm) of the filter and connects the smaller hose (4/6) to the tank to be supplied with water. Alternatively, the Multi Flow can also be used to supply CO2 reactors or the direct feed of CO2 into the aquarium.
