Rox Carbon Chemists Opion Needed

[roxsburyrage]

I was wondering if some of the Chemists out there could tell me if Rox Carbon is really better to use on Aquariums or was it meant for other purposes.I have heard rumors that it does not work that well for what we use it for.
Maybe Randy Holmes can chime in Thanks
