I have the 206 and service it about once a month.
I do the whole cleaning thing in tank water, in a bucket.
1. Take the red sponge tray out and squeeze the sponges in the water, put them back in the tray and to one side.
2. I have a bag of carbon in the top tray, I clean the bag and replace the carbon granules.
3. Replace/clean the filter floss by squeezing it in tank water then reassemble the media tray.
4. Rinse the ceramic bio-balls in tank water, in the tray and put to one side with the sponges and the filter floss tray.
5. I replaced the bottom carbon foam for Bio-foam and I simply squeeze that out in the water and replace. If I had the carbon foam pads, I'd replace them once a month.
6. Unclip the impeller cover and rinse it off. Click the impeller cover again.
7. Empty the old, partially filtered water into the toilet/bath tub/where you put your old water.
8. Reassemble the filter and get it functioning again after the water change.
I am meticulous when cleaning my filter and do everything by the book. If there's one thing I don't want an issue with, it's the every day running of the filter. The only thing I don't do regularly is clean the tubes because it's a headache in the form of slimey, smelly gunk that you thought you'd never have to deal with when entering the hobby.
