purigen takes out tanins. So I really would not use it in a blackwater set-up. Think of it like this...You add peat to get tanins then add purigen which will take them out...So why add peat in the first place?
Not trying to sound like a riddle,but I hope you get the idea.
Purigen is a great media...However I don't think it is right for your situation
It also removes nitrates so you know. |
