How do you test water for calcium hardness?
Total Hardness: To test your pool water’s hardness, dip a test strip 18 inches below the water surface or as directed by the test strip manufacturer. Remove the strip and wait for the color to change and indicate the level of hardness. Ideal levels of water hardness rest between 200 and 400 ppm.
How do I know if my pool needs calcium?
Low Calcium Hardness Eroding of tile grouting and delaminating of plaster surfaces. Etching or pitting of pool decks or stone and concrete surfaces surrounding your pool Corrosion of metal parts (i.e. pipes, ladders, filters, screws, etc.) Pitting of concrete pool flooring and walls.
What should the calcium level be in a pool?
The ideal range for Calcium Hardness in swimming pools is 180 – 220 ppm, although others may use 200-400 as an acceptable range of hardness.
How do I remove calcium from my pool?
The best ways to remove calcium carbonate is to use a calcium releaser/cleaner, preferably an acid-free product, so it doesn’t ruin the finish of the pool tile or glass. Next, you can try using a pumice stone or scale remover.
What’s the best way to test for calcium in a pool?
The most accurate way to test calcium hardness is with a water hardness test kit. You can find inexpensive water hardness test kits, or more useful pool test kits that provide a wide range of water tests, including a test for calcium hardness.
Why is the calcium hardness of my pool so low?
Pool water with calcium hardness too low might appear sparkling clear, when in reality the water is actively corrodingsurfaces of your pool. This is one reason to test your pool, even when the water is clear and appearsbalanced and healthy.

How do you test the hardness of a swimming pool?
Swimming Pool Calcium Hardness Test Methods. With the correct testing tools, calcium hardness is easy to test and you can quickly determine if you have soft, hard, or balanced pool water. Calcium hardness testing is easy with test strips. Earlier test strips for testing hardness only could test total hardness, meaning calcium plus magnesium.
How do you increase the hardness of a pool?
Adding calcium chloride is the most common way to raise swimming pool water hardness. First test your pool for calcium hardness. Determine how many ppm you are from the midpoint of the ideal calcium hardness range. Calcium chloride is the main chemical used to increase water hardness for pools.
How do you remove calcium from pool water?
Quite simply, the best way to remove calcium from your swimming pool is by using Reverse Osmosis (RO) filtration. Most people are quite familiar with RO to provide drinking water and the small tanks that typically sit below your sink.
What is calcium hardness in pool?
Calcium hardness is the measure of how hard or soft your pool water is, and how much calcium is dissolved in your pool water. Ideally, you should strive to have your calcium hardness levels at 200 – 400 ppm with your ultimate goal being to try to keep it right in the middle of that figure.
How much calcium in pool water?
The proper level for calcium in your pool will depend on the type of pool surface you have. Vinyl liner, painted and fiberglass pools will need at least 170 ppm of calcium in the water and levels up to 400 ppm are acceptable. Concrete pools will need a higher starting point of at least 225 ppm.
