At the same time as cleaning the filter, I pump out anywhere up to 25% of the pond water (my pond is ~800 liters), normally maybe 10%. This is normally every week.
To fill the pond back up I add some Tetrapond Watersafe Pond Water Treatment and then top up with tap water via a hose.
I can't remember getting anything but 0 or next to 0 ammonia and nitrite, especially since the pond was first set up. The nitrates have never got too high. I have always assumed the regular water replacement, and the high number of plants in the pond have always helped.
