My statement about (perhaps) changing the water every couple years was solely related to the concept of controlling exceedingly high CH levels. Some in the SW with really hard water simply can't avoid it depending on the CH content of their fill water and refills due to evaporation. For those who must change some water to control CH, naturally other products would be removed as well. But in general, water doesn't go bad or arbitrarily need to be changed.
