Advice on external filter

[Markiep]

Hi ive just recently started using my aquael external filter, I'm use to internals.
Sorry if this is a stupid question, but when doing normal pwc do I turn the filter of like unplugging it? Not sure what to do!
Thank you

I agree with not overcleaning your external filter except for. If you are using carbon to remove medication or ammonia/nitrate/Nitrite pads, if you leave these too long they can release the contaminats back into your water. be sure to read the instructions.
