OK, my friend Joe (joekool) here asked my take on Sea Chem's Purigen product and have not until today even researched it. After reading through all info on Sea Chem's website seems like a very ingenious product so would like comments/feed back from any one currently using it on there Marine System(s) including results ie; reduction of NO2 & NO3, size of system (total water volume), amount of Purigen used and its longevity before needing to be regenerated.
Cheers, Todd
