What is water chemistry when we are talking about pool water?

About 90% of all pool problems arise from faulty water chemistry.  The chemistry of your pool water is constantly changing or being altered because of rains, hot spells, heavy bather loads and even falling leaves or grass clippings.

What does it mean when they talk about water balance in my pool?

Water balance deals with the tendency of water to corrode or scale. Water Balance tells us one of three things:

Is the water scaling?

This means does the pool water precipitate or deposit a crusty, white substance called calcium carbonate or scale? This is the same as the deposit one sees at the bottom of a kettle used to boil water. Scale formation can form abrasive deposits on the pool surfaces, plug filter sand, reduce circulation by depositing scale inside the piping and cause cloudy pools. Allowing a scaling water condition to continue does irreparable damage to pool surfaces and equipment.

Is water corrosive?

Most pool owners understand the concept of “corrosion” Rusting is an example of corrosion of steel. In the pool environment corrosion can mean pitting of concrete surfaces, dissolving copper elements inside the pool heater or pin holes in metal filters and piping.  The only way to correct corroded equipment or pool surfaces is by replacement… a very expensive proposition.

Is the water balanced?

Balanced water is neither scaling nor corrosive and does no damage to pool equipment or surfaces.  Obviously, our objective is to have Balanced Water!  There are three main factors or parameters which determine if water is balanced or not.  There is pH, Calcium Hardness, and Total Alkalinity.
