In The Swim Calcium Hardness Increaser For Swimming Pools

Don t let your water become too soft with In The Swim s 45 lb Bucket 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 Maintaining proper calcium levels ensures the longevity of your pool s surfaces and pool equipment to help protect them from corrosion and scaling. Calcium hardness is not as well-known as some other pool chemicals but just like the rest it needs to be monitored for optimal pool performance. When calcium is below 150 ppm start to add about six pounds per 10 000 gallons of In The Swim Calcium Hardness Increaser to raise the ppm by about 50. The recommended range for pool water calcium hardness is around 180 – 220 ppm. Just remember to not add too much Calcium Hardness Increaser. It is important to keep calcium hardness below 400 ppm. Hard water has too much calcium and magnesium which can then lead to scale deposits onto your surfaces lights and ladders and can make the pool water cloudy in appearance. Avoiding Calcium Scale It is important to keep calcium hardness at the proper levels. If the calcium hardness level is too high it can cause potential damage to pool interior surfaces as well as damaging the pool equipment. When too much calcium is in the water calcium scaling can become present. Calcium scaling can appear along and above the waterline forming a white crusty scale build-up around the pool. When using Calcium Hardness Increaser it is best to stay under 400 ppm. High calcium levels is the most common cause of calcium scaling but high Alkalinity pH and high water temperatures can also contribute to scale build up. In that state you should use Acid Magic or Instant Liquid Acid for a safe solution to dissolve calcium scale buildup.
