Don't let your water become too soft with In The Swim's 5 lb Bag of Calcium Hardness Increaser. When calcium gets too low your pool surfaces can become corroded, scale deposits start to grow, and the water in your pool will begin to look cloudy and dull.
Proper Levels for Calcium Hardness
Calcium Hardness is not as well known of the chemicals that lurk in your water, but just like the rest it needs to be monitored to have peak performance in your pool. When calcium is below 150 ppm start to add about six pounds per 10,000 of In The Swim's Calcium Hardness Increaser to raise the ppm by about 50. The recommended range for calcium in your water is around 180-220 ppm. Just remember to not add too much Calcium Hardness Increaser. It is important to keep the ppm below 400. Hard water has too much calcium and magnesium and they can deposit onto your surfaces, lights and ladders making the water cloudy.
Avoiding Calcium Scale
It is important to raise Calcium hardness to the proper levels but too much can be damaging. When too much calcium is present, calcium scaling can become present. Along and above the waterline forms a white translucent crust along your pool. When using Calcium Hardness Increaser it is best to stay under 400 ppm. High calcium levels is the most common cause but high Alkalinity, pH, and high water temperatures. In that state you should use In The Swim's pH Increaser, Acid Magic or Instant Liquid Acid for a safe solution to dissolve calcium scale build up.
