hth calcium hardness increaser is used to raise the calcium hardness of swimming pool water. Low calcium hardness may cause the pool water to be corrosive, resulting in damage to pool surfaces and equipment. Plaster finish pools may be etched or stained if the calcium hardness of the pool water is not properly adjusted. The calcium hardness of chlorinated pool water should be maintained in the range of 200-500 ppm. Application directions: 1. Measure the calcium hardness of the pool water with an hth test kit or
2. Use the chart below to determine the amount of hth calcium hardness
increaser to add to your pool. Generally, 1 lb. of hth calcium hardness increaser
will raise hardness by 10 ppm in 10,000 gallons of pool water.
3. Broadcast evenly over the pool surface with the pump running. Brush any settled
material to ensure it gets dissolved.
4. If a large amount of hth calcium hardness increaser is required (an increase of
more than 50 ppm calcium hardness), add 1/3 of the appropriate dose per addition.
Wait 4-6 hours between additions.
Test Your Water
How often you should test and balance your pool can vary based on how often you use it and a number of other variables, but it’s important to remember that, for chlorine and pH, you should usually test your pool two to three times a week. That may sound like a lot, but water balance is vital for your pool’s health and the health of the people who swim in it. When your pool is out of balance, your sanitizers can be less effective, the water can cause irritation to the skin and eyes, and if the water gets imbalanced enough, it can even damage the pool’s surfaces, structure, or equipment.
In ideal circumstances, shocking your pool just once a week will keep it looking clean and clear, but any heavy rainfall, signs of algae, use by lots of swimmers, or periods of very sunny weather can deplete free chlorine levels, which means an extra dose of hth Shock is needed.Sundown is optimum time to shock your pool because the chlorine can work without fighting the sun's ultraviolet rays and has more time to restore water clarity.
