Do I "clean" the filters in my three stage fluval aquaclear,

[Electus unus]

Or just replace them on the corresponding months? If I'm to clean them, I basically just rinse them in a bucket of the tank water, yes?

Correct, for your weekly cleaning, you can rinse them out in tank water, if you are using that as part of your biological filtration. If you are just using the filter to remove debre then you can just rinse em out with the hose. Should be done weekly to keep the Nitrates from creeping up.
