Primitive technology: build tank fish, fish pond - water filter tank (part 3)

Hello. build tank fish, fish pond - water filter tank (part 3) is our next video. In this video we build a waterfall and design a water filter system for the aquarium. We drain the water from the large filter tank into the fish pond and filter the dirty water with a small filter tank. Fish ponds will be a good place to store food. We will continue to make the next video on primitive technology and wild survival skills. Subscribe to the channel to keep track of the latest videos. Thank you. channels: https://goo.gl/vvCuGR
