In the past, I went a while with no water changes, using an algae scrubber.
Similar to Triton I guess, but before a specific method existed.
Fish were fine. Tank was fine for a long time, then started to degrade.
It turned into a big headache of testing / adding / tweaking.
My base theory: The algae scrubber was to strong, and it was stripping nutrients and trace out too fast.
So my opinion on Triton: It can work fine.
But done a bit wrong, you can end up with endless test/tweak hassles.
Also, if you are thinking of big changes, consider an auto-water-exchange system.
One time hassle of building it. But then it becomes very easy.
