I have this Juwel Vision 180 with the internal filter. It has been running for 4 weeks and fish have been in there since 1 week. Water test turn out good but I want to change filters. I bought the Oase Biomaster 250. Do I have to keep both filters on for a few days or weeks or will it be fine to shut off the internal and get it out after a certain time. Thanks!

I recently changed filter and this is what I’ve done (successfully): get yourself a bucket, fill it aquarium water. Squeeze out all of the filter media of the old filter inside that bucket. Put in the new filter, turn it on and wait a few hours before the water is completely clear. All of the bacteria is now in the new media
