Hello,
I'm wondering if you could help me clear up some contradicting advice... We have recently converted a jewel Rio 180 to a marine tank. With regard to the internal filter, are the filters/ sponges required eg the nitrax etc? The phorax works brilliantly but I have been told the others are wasted.
Thanks in advance
