It works pretty well. It is easy to regenerate. Just work beads (which must be placed in media bag) into some water with table salt. The salt will soak up the wastes contained in the resins. Must be recharged once a week. Doesn't do anything about strong smells. Lasts about 2 years. Good alternative to carbon, but, in the end, I end up using carbon as well to alleviate odors.
