I saw someone recommend using Purigen recently. I have a rena smartfilter & aquaclear 70... Should I use the Purigen in the tank with these 2 filters or is that overkill? The tank is a 75 gallon.
Well the one I asked about is a 75, but I just moved fish into a 300 gallon in my office on Thursday. Should I use Purigen in that one right from the start?
