> 3 dayI use it for a month and then rinse it out real well with fresh water and its ready to go for another month. Use it on my saltwater aquarium and does a god job.

> 3 dayThis is a great product although this is the first time I am using it. I used to use activated carbon that comes with filter refills. Matrix carbon is much superior in performance and delivers better results. I have a bio filter submersed in the tank ( not a bio filter in the mechanical filter).

> 3 dayThis stuff is great! Instead of cylindrical bars or chunks of carbon, this is tiny beads of carbon. Rinses clear in seconds with very little dust particles. You dont need much either, half a cup for 50 gallons or so. I used to have to fill a mesh bag to get the same effects as this stuff.
