How to make an Aquaponics filter (Hybrid aquaponic system)

In this video I show you how to make a mixture of a mechanical filtration and settling filtration system. I do not know the name of it but it works for aquaponics. You can see the concept in the video.
The front pipe is just an overflow in case anything gets clogged. It goes directly to my sump tank. Water enters first in the swirl filter through the back which you can't see. It then passes through a 2" pipe in between both barrels to the mechanical filter. And from there it goes to the grow beds.
