Many parts of the US have hard water which can leave calcium deposits at the waterline on the pool walls or floor.
Calcium carbonate scale can form along the waterline of the pool as evaporation increases during the warm weather. It is a white translucent color, but is often mixed with dirt and algae to appear darker in color.
The most common cause of calcium scale in pools is the consequence of high calcium hardness, yet it is set off by high Alkalinity, high pH and high water temps.
Call your Maui swimming pool service, Ohana Pool & Spa, for a check of your pool chemicals or to remove your existing calcium scale.
Our services include weekly Maui swimming pool cleaning, maintenance, chemicals, repairs, inspection, plaster and resurfacing of your existing swimming pool.
