Understanding Basic Chemical Levels

Owning and maintaining a swimming pool can seem overwhelming at first because there are a lot of new tasks and concerns to deal with. New swimming pool owners often feel overwhelmed by all the new information. One important aspect of the process is understanding the chemicals involved in managing a swimming pool. It seems like a lot to learn, but there are five basic chemical elements that pool owners should understand.

The first chemical pool owners need to understand is free chlorine. It is often referred to as FC.  This is the sanitizer that keeps your pool water free of germs and safe. The free chlorine has to be chlorine has to checked and replenished on a regular basis. pH is an important part of taking care of a swimming pool. It is often as the aciditiy or alkalinity of the water. Maintaining the pH of the water is important because if it is out of balance, it can irritate swimmers’ eyes and skin. Appropriate pH levels also protect your pool equipment.

If you maintain the appropriate levels of total alkalinity, it will help to keep your swimming pool’s pH levels in balance. If the total alkalinity levels become too high, the pH levels will rise. You should test the total alkalinity regularly but it should stay stable in a well-maintained pool.

Many people don’t understand the importance of calcium hardness when it comes to taking care of a pool. Calcium hardness is particularly important if you have a plaster pool. If the calcium hardness is too low, the water will become corrosive. The pool’s floor and water can become stained and the pool’s surfaces can be etched by the corrosive water. If the calcium hardness is too high, calcium scale will form. The pipes and filters will get clogged which affects water filtration and efficiency.

Cyanuric acid is the final basic chemical element that pool owners need to understand. Chlorine is significantly affected by the UV rays in sunlight. Balanced water can lose its chlorine level quickly in strong sunlight. Cyanuric acid is often referred to as a stabilizer and protects the chlorine in the water from sunlight.
