is a controlled environment. You have to control the temperature, the water flow, the acid levels, the alkalinity levels, etc. Of course, you have automated systems in place to do most of the job for you such as heaters, pumps, filters, controllers, etc. But even these systems need to be adjusted every now and then to make sure that they're doing their jobs correctly.
For example, a monitor for salinity regularly checks the water for its salt content. It makes sure that the salt content is constant. The system is calibrated to recognize the accepted levels or the standards. But in time, the readings will become less and less accurate and will deviate more and more from the standard. When it reaches that point, it doesn't mean you have to throw away your system and buy a new one. No. It just means that it's time for recalibration.
