in my 55g and i was wondering how much filtration im getting per hr. is it a lot over 55gs or just decent? Its the 30-60 thing that confuses me. flow rate says 330/1249. So if I have two on my 55 is that over filtration? Is this sufficient enough for anything ide like to keep?
Thx again for the help guys!
