Which one for my Rena filters. Personally I like the Bio Chem Zorb. I read that the only difference is that you can recharge Purigen a few times. I used Purigen before in my HOBs but, I do not want to go through the trouble of recharging it.
I have a feeling that everyone will recommend Purigen. Anything bad about the Bio Chem Zorb ?
Lol, I have both in my shopping cart right now waiting to pull the trigger.
