In this video I show you how to make a swirl filter for my aquaponics system. I use a 55 gallon drum which you can buy on craigslist for pretty cheap. As well as uni-seals, and PVC pipe + fittings. It helps get many of the solids out of your aquaponics system. The swirl it creates causes the solids to settle on the bottom of the barrel.
