How do you know if your pond is healthy if you never test it? Clear water doesn't mean healthy water any more than Green Water means unhealthy water. Water quality imbalances do not always produce immediate change in fish behavior, some damage is cumulative and will evidence itself only when it is too late for a remedy.
I agree but as long as my water is clear, fish healthy, Water lillies green and blooming I have no need to test. Most people have no idea of the chemistry of water and start adding chemicals to correct one problem only to create another problem. On another note, if a pond is simply in place to hold water and not life, why not install UV to at least keep it clear?
