I also change about 20% of the water in my tanks every 5 days to help control the nitrates in my tanks. But found it interesting that you could build a filter that would remove nitrates naturally WITHOUT any use of chemicals or plants.
After reading some posts on pond message boards, some people have large ponds or indoor ponds to keep the fish from the winter elements. If you had to do a water change on a 10,000 gallon pond or a 300-500 gallon indoor pond that would be insane amount of water to try to change weekly but building a trickle tower to help control nitrates naturally is a great idea
