Specification Brand : In The Swim BulletPoint1 : Quickly raises the calcium levels in your pool to prevent low calcium levels that can cause erosion, pitting, and etching of pool surfaces. BulletPoint2 : Excessive use of calcium hardness increaser can lead to scaling and blockage, potentially damaging pool equipment. BulletPoint3 : Maintain proper calcium hardness for improved pool water quality. BulletPoint4 : The recommended range for calcium in your water is around 180-220 ppm. Keep the ppm below 400. BulletPoint5 : Add around 6 pounds per 10,000 gallons to increase hardness by approximately 50 ppm. Apply if hardness drops below 150 ppm. Color : Multicolor Directions : 1. Test the calcium hardness level in your pool. 2. Add 6 pounds per 10,000 gallons of water to raise the hardness level by approximately 50 ppm if the level is below 150 ppm. 3. Apply the product if the hardness drops below 150 ppm. 4. Keep the ppm below 400 to avoid calcium scaling. 5. Use In The Swim's pH Increaser, Acid Magic or Instant Liquid Acid for a safe solution to dissolve calcium scale build up if calcium scaling is present.

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.
