Review on Continuum Aquatics Detritus Freshwater Aquariums by Jeremy Ward

Maybe it's enzymes, but for the first time the oily film on the surface of the water in my aquarium disappeared within a few hours. Also, compared to other products, you can actually see the contents of the bottle. So it's probably more concentrated and doesn't smell bad. The only thing I didn't like was the instructions, they make it seem like you have to add this forever. Instead, I went on a maintenance dose.
