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.
Turn your filter on and allow it to circulate the water. Use the water testing kit to retest the water for calcium hardness levels. The calcium hardness level should be reduced with the addition of new water. Check and balance the other pool chemicals such as chlorine, alkalinity and pH. Wait 24 hours and monitor the results.
