Intresting system. It could help though couldn't it? Not to eliminate water changes, but to aid in the nitrogen cycle?
Perhaps even when making a new tank. Set this up from an old tank into it, and let it start the nitrogen cycle. I'm probably wrong though...
Didn't know that I was also removing other stuff when I did my water change! No wonder my AQ water is harder than my Tap
