Just saw this yesterday and was wondering what are other people's take on this here.
I am on the same boat as to not be chasing parameters in order to favor stability but im not entirely sure about going a month or more without wc. Especially with big fish.
Unlike a natural environment, an aquarium is a “closed system.” Imagine that you were locked in a sealed room for even one week. You were expected to eat, sleep, breathe and carry out all of your activities and bodily functions in that room. For me, no further discussion is required.
