Hi
I have had my aquarium (cold water) for about 6 months and change the filter media regularly but am unsure as to whether I should change the bio-rings as have read that they should be left alone as the bacteria on them is essential to the biological filtration. Does this mean they should never be changed?
Any advice would be appreciated
Thanks
Tammie
