There is still some confusion about ecoBAK and it's relation to other bio-polymer products so I just wanted to clarify a bit. A few years ago we watched the European company introduce it's pellet product and thought what a fantastic idea it was. At that time (unlike today) no one had any idea which polymer or co-polymer was used in the pellets. So I started my research fresh, untainted by trying to copy an existing product. I ended up with a polymer that as it turns out was NOT the same polymer used by the original and the subsequent packagers of polymer pellets. I liked my polymer so much I wrote and applied for a patent. So here we are a few years later and we've all seen the user reviews of the other brands of polymer pellets which are "so-so" at best and the reviews of ecoBAK which are still 95%+ positive. This isn't a coincidence, there's a physical difference between the products. ecoBAK not only reduces Nitrates and Phosphates but also reduces other dissolved organics, clarifies water and produces bacterioplankton for coral food. ecoBAK allows users to feed their systems without fear of elevated nutrients and allows users to keep more fish in their systems... ecoBAK works and I'd like to thank the 1000's of users that have trusted ecoBAK and made it the best reviewed, top selling polymer pellet on the market.
