| Re: Purigen I have tried Purigen before. I notice that it does not work for my tank. I do not get any colour change as descript by some of the pics here.
I have also tried Zeo (stone base) Nitrate removing filter media and again I find that it does not work very well too.
Now I uses the Aquamedic denitrator (deniballs base) and it rocks. It does take some time for the filter to mature and once its does, u are ready to rock and roll. |
