Why do I get calcium readings in my Pool?

But calcium is consistent. The measurement you get at one moment may have nothing to do with the current condition of your surface or equipment. It is more likely that a water balance problem presented itself over a long period of time; not the moment you are testing the pool.

What happens to a fiberglass pool liner in calcium deficient water?

That is to say, in calcium deficient water, a plaster surface gives up necessary surface calcium to attain equilibrium with the water (causing premature surface failure). So yes, liner and fiberglass pools may not etch the way plaster does, but they will degrade.

What happens if you have low calcium in Your Water?

Low calcium water in vinyl or gelcoat/fiberglass surfaces continues to create more corrosive water. There is no mechanism to improve the buffering power of calcium and will therefore cause plastic to become more brittle and gelcoat to chalk and degrade or etch.

What should the calcium hardness of a pool be?

All other measurements are identical. The difference between a pool that is corrosive or not simply relies on a higher calcium hardness level. By the way, the aggressive reading on the left of the screen has a industry-acceptable level of 200ppm Calcium Hardness.

Why does my swimming pool have too much calcium?

For vinyl liner and fiberglass pools, the sources of calcium may not be there at all, which is why these surfaces can get faded and damaged by aggressive water. The water is starving for calcium. On the opposite end of the spectrum, high-LSI water has too much calcium carbonate, and deposits it out in the form of carbonate scale.

Why is my Pebble pool finish turning white?

The most common maintenance issue is scaling (a white haze) on the pool finish surface due to poor water chemistry. The water chemistry in your swimming pool and/or spa must be maintained at certain levels to prevent scale build-up.

Where does the calcium dust in a pool come from?

Calcium dust comes from a different place, with different chemistry involved. Calcium dust can be formed in a few different ways. The most common form is called plaster dust, where low-LSI tap water fills a newly plastered pool and begins dissolving calcium in the cement.

What should I do about my Pebble pool finish?

The water chemistry in your swimming pool and/or spa must be maintained at certain levels to prevent scale build-up. Scale can also trap dirt and debris, further discoloring your finish. Scale removal is not covered by warranty. The most common method for removing scale is through chemical treatment.
