The "Poly Filter" is a superior product that exceeds the manufacturer's specifications. Quality control is excellent and consistent, and the manufacturer is available for technical assistance in specialized applications. It offers hobbyists decided advantages over all other chemical filtration medias.

In 1998, now more than twenty years since its introduction, the "Poly Filter" is better than ever. It has undergone numerous improvements which in 1997 resulted in a new patent. Some of those improvements include more surface area and faster rates of absorption/adsorption which mean improved functioning efficiency. In addition it has compiled an impressive amount of test data to substantiate its product claims under U.S. EPA (Environmental Protection Agency) standards and test methods. There is no product quite like the "Poly Filter". It Just Makes Keeping Fish Easier!
