Seachem likes to support brick and mortar stores so they exclusively let them deal with their aquavitro line. If you are like me and your nearest LFS is 30 miles away and they only carry saltwater AV products, you are kind of screwed if you want the better stuff.
Someone could do an easy test. Get two reactors, put purigen in one, Purfiltrum in the other and run them side by side.
I think purigen's efficacy decreases about 10% each recharge. It might just equate to recharging it once more before it needs replacing. I am only ever able to recharge it two or three times before it looks about through.
