Hey everyone! So I read way too far into a piece of information presented to us in Pokemon Alpha Sapphire.

“The hardness of Kalo’s water often exceeds 300 ppm. That’s characteristic of the water in Kalos.”

Now, for those of you that don’t know, the ‘hardness’ scale of water has to do with the amount of particles within the water that give it certain qualities. Water from 0-150 ppm (parts per million) is normally fine and is mostly natural, whereas water anywhere from 150-200 ppm are recommended with the use of a water softener, and anything from 200-300 has it as absolutely necessary to use a water softener to halt severe limescale buildup and premature degrading of pipes and systems that transport water.

But what does that have to do with anything?

Well, the main minerals that cause water hardness are calcium and magnesium. Incredibly high hardness levels occur around areas with a lot of limestone which contains these minerals that seep into the water supply.

Limestone itself is normally formed by dead animals, primarily sea-life.

3,000 years ago in Kalos, AZ wiped out most life in Kalos with a giant space laser.

Which then formed into the limestone deposits that form the land of Kalos and affect the water around it.
