Casco is back in the news again with another new product simply called Pure. Pure Media is a biological media similar to the Fauna Marin Bacto Balls but it has a much larger form factor for very large aquariums or retail store fish systems.

Pure Media is almost the size of a tennis ball whereas Bacto Balls are about the size of a standard marble. The media is simple to use. To use the media, simply place it in the sump of filtration area where it will slowly dissolve as it goes to work. After 1 month drop in a new sphere of Pure Media and the process begins again.
