How do I lower calcium hardness in my pool?
There is really only one way to lower your pools high calcium hardness level and that is to partially or completely drain your hard pool water and replace it with fresh water.
How do you lower the hardness in a pool?
How to Lower Calcium Hardness in Your Pool
- Drain and replace some water. Before you replace the water, test your water source.
- Use pool flocculant. If you can’t or don’t want to drain any water from the pool, try using pool floc to clump the excess calcium.
- Try muriatic acid.
What can I use to lower calcium levels in my Pool?
The normal method is to drain a portion of the pool and refill with water that has been treated with a home water softening system, or from trucked-in water with a lower calcium content. Captured rain water, which has 0 ppm of calcium hardness, has also been used by some as a means to reduce calcium levels.
What should the calcium hardness of my Pool be?
Calcium hardness is the measure of how hard or soft your pool water is and how much calcium is dissolved in your pool water. The perfect calcium hardness level should be at 150 – 400ppm, ideally getting it between right in the middle of that range.
What’s the best way to lower calcium hardness?
This is the best way to permanently lower your calcium hardness level, but it does call for a bit of extra effort. The logic behind this method is dilution, or rather, “watering down” your pool water with new water. Specifically, filtered water with low calcium levels.
Why do I need to increase the hardness of my pool water?
Maintaining proper calcium hardness is essential to keeping your swimming pool in good working order. Soft water (low calcium levels) can cause plaster or concrete pool walls to lose their calcium to the pool water, and can cause vinyl pools to lose their elasticity.
How do you reduce calcium hardness in pool water?
Add muriatic acid if you need to lower the alkalinity of the water. If you find that your calcium levels are still high, you can adjust the alkalinity of the pool to control calcium hardness. For a pool with high calcium levels, add 2-3 capfuls of muriatic acid to lower the alkalinity to around 80.
How do you increase calcium hardness?
Measure out enough calcium chloride to raise the hardness level. Use 1 1/4 pounds of product per every 10,000 gallons of water if you need to raise the level by 10 ppm. Use 2 1/2 pounds (per 10,000 gallons) to raise the level by 20 ppm, or use 6 1/4 pounds of product (per 10,000 gallons) to raise the hardness level by 50 ppm.
How does calcium help a swimming pool?
Calcium does several things for you; first it helps the filter be more efficient at doing its job to the best of its ability. If your calcium is too low you may have difficulty getting your pool to clear. The other reason it is important relates to the other mineral balance in your pool, total alkalinity.
Is calcium hardness important for a concrete pool?
Calcium Hardness cannot usually be tested with the standard 4 in 1 test kit so you will need to take a water sample to your nearest pool shop or use a mobile service technician for testing. Calcium is particularly important in concrete pools as unlike fibreglass or vinyl pools concrete is porous.
