re: : How precise is good enough for a pH measurement?

James,
many people, me included, have spectacular tanks with only the occasional
chemical-based "El Cheapo" pH measurement with, at best, 1 pH point
precision. So is the extra precision in the Piccolo needed? No.
Is the water in nature precisely regulated? No. Even in the same water
course the pH changes constantly.
I think you must answer your question "is it worth it?" using other, more
personal factors. (Fearing frightful flames, I refrain from further
reflection on these factors). :-)
