My name is Sean Li, and today I’m gonna show
you how I feed my fish in my Aquaponics system for free using duckweed. And with no effort.
And you can build this yourself if you want to. And here is the idea: You connect the
container where you grow the duckweed with the fish tank, with two canals. You put one
canal inside the other one, so you can pull it out. And then the fish will swim in underneath
it and eat from the hole that you made in the first canal. And by adjusting it in and out
you decide the amount of food that is available for the fish depending on how many fish you have that week or month. Inside the container of the duckweed, you should have some media in the bottom. This will help the bacterias convert the fish poo into nutrients for the
duckweed, which is floating on the surface. Duckweed grows really quickly. So within four to six days, it doubles itself and it just push itself into the fish tank. And you don’t
have to do anything. I hope you enjoyed it!
