Pre filter question

[Elephant nose 4]

Hi I have an aquael ultramax external filter and it has a pre filter at the top.
How often would you rinse the pre filter sponge out in a bucket of tank water? I did it last week and wondered if it should be a weekly thing.
Thanks

every week if possible to stop it blocking up and slowing or stopping the flow of water into the filter.

I think that can be included best by you for your specific circumstances. I have mesh prefilters in all my filters (10 AC110,s, 2 fx6, several others). I clean all prefilters weekly in sink water. For others, in other tanks? Who knows….

I have prefilters on my filter inputs, and I have to rinse them out every week in most cases so as not to prevent input flow.

Thank you everyone for your help
I thought weekly would be best so that's what I did.

Yes. Since it's the first media of the filter, it can get pretty gunked up.

I do it every week when I do my water changes because moss always gets stuck in them I also replace them about but every six months
