It tends to be lower in summer when the temperature is high because the chlorine evaporates more easily in higher temperatures, and the concentration tends to be higher in the winter when less chlorine evaporates because the weather is colder. As for location, the chlorine concentration is higher in urban areas and areas closer to water treatment plants.

In addition to this, given that chlorine is designed to sterilize water, it is obviously harmful to microorganisms including beneficial bacteria that living in the biological filter media and aquarium.
