Hi every1 again, im confused, i was under the impression that the blue pads were the polishing pads and the white were the main filtration pads, but is it the other way about??????????? please help lol

It depends what filter you are using. Canister filters normally have biological filtration, and mechanical filtration included in the package. In many cases the biological filtration is what resembles little balls, or cylindrical rings. The mechanical filtration is often the blue sponges. Then you get a very fine white pads that catch very small particles. These will get dirty very quickly which is why I never use them in a canister filter because if you've got quite a lot of fish you have to change them once a week

on the fluval, the small white pads you can buy that fit in the small boxes are for water clarity. They should be placed in top basket!
