DIY Koi Tank Upgrade: Build Your Own Barrel Filter for Crystal Clear Water.

In this video we will walk you through the process of building a three barrel koi tank/pond filter system. Our system uses three 23 gallon barrels and contains 4 cubic feet of K1 filter media. The system contains a swirl filter, radial flow settler, static filtration and a moving bed filter. This one has it all.
