i have a top fin filter that takes 2 catridges. PetSmart told me to change the cartridges once a month, but i have also heard that is not needed.
a friend told me to change them when water no longer can pass thru them, and then only change one at a time abou a week apart cause of the cycle issue.
so what is the recomended best way and time to change them.
i also put extra carbon in the filter bag im not sure if that makes a difference though.
as always thx for your help
