| Mike, as I said previously, this is a great thread and you have made the very best of posts. But I fear now you are moving away from the big picture with this example.
we all agree that water changes are the method that brings water back to the ideal base line parameters where koi can operate and grow uneffected by outside negative factors of pollution , gas imbalance, pH decline, hormonal feedback and mineral interference.
But The water change is also the demarcation line between open systems and closed systems. This is important because this is the moment where systems change in regard to the level of microbal dependency. THIS is the real point of equilibrium. The balance between fish and microbe is what makes for the rate of deterioration and exhaustion fo water.
So I would not call the water change a point of equilibrium without making it clear that 'equilibrium' is a term meant to describe the relationship between fish mass and microbes. And water changes return parameters to ideal base line readings. - JR |
