Water hose assembly with flow control valve. They have a bypass valve ideal for supplying breeding tanks, such as Nido 4 or Nido 5, providing a continuous supply of fresh filtered water high in oxygen. For this purpose, the Multi-Flow is simply connected to the filter hoses, and the smaller hose is connected to the tank that is supplied with water.
Optional use: the Multi-Flow can also be used to supply reactors with CO2 or a direct supply of CO2 to the aquarium for planted aquariums
