The Multi Flow is a smart water line connector with an adjustable flow valve and bypass functionideal for supplying breeding tanks like the Nido 4 or Nido 5 with a constant stream of fresh, oxygen-rich, filtered water. It connects easily to filter hoses, delivering water directly to the breeding tank via a smaller tube.

It can also be used for CO applications, such as feeding CO reactors or providing direct CO injection into planted aquariums.
