5 things you have to know about German guys: 1. They are responsible. Of course Iâm generalizing in all of these points. But every generalization is partly true. They like having fun, but only when itâs appropriate. If you come from Latin lands and shout when talking, youâll scare him.
The ideal range for calcium hardness is 250-350 ppm. If the calcium hardness is too low, the water becomes corrosive and results in the etching of the pool's surfaces. Metals corrode - and this includes pool equipment, pipe fittings and pump connections. As a result, the pool's walls and floor can stain.
To calculate how much calcium chloride your swimming pool requires to increase the calcium hardness, choose the increase you want and enter the volume of your swimming pool. Desired increase in calcium hardness 10 ppm 20 ppm 30 ppm 40 ppm 50 ppm 60 ppm 70 ppm 80 ppm. Volume of the pool ,000 litres.
