Pool Cleaning - Pool Chemicals

This is the 4th installment of the “14 Ways to Make a Splash with Pool Safety which is available as a Free download from our eBook library.

How often do you perform pool cleaning? If you are confident with balancing the water chemistry in your pool, then you can test the chemicals yourself. Every week, you should test your swimming pool for chlorine and pH.

Chlorine tests include three separate measures:


  1. The level of free available (or residual) chlorine. This is the amount of chlorine that keeps the pool water clean and safe.
  2. The level of combined chlorine. If there isn’t enough free available chlorine,you may have the undesirable combined chlorine. It might make your pool give off a bad odor.
  3. The level of total chlorine. This represents a combined measurement of both types of chlorine listed above.

If your pool doesn’t have a sufficient level of chlorine, your water will get dirty and can lead to algae or bacteria growing in your pool. Those, in turn, can cause illnesses for swimmers. If your pool has too much chlorine, you face another set of problems. Swimmers will notice irritation in their eyes, nose and skin. Chlorine is a powerful chemical that can be very harsh when administered in the wrong quantity.

14 Ways to Make a Splash With Pool SafetyThe other half of your weekly pool cleaning & testing monitors the pH level of your water. A pH measurement tells you how acidic or alkaline your pool water is.

If your pool is too acidic (has a low pH), you risk damaging the surface of the pool and corroding any metal fixtures. Acidic pools will often show brown or black stains caused by this type of corrosion. Swimmers might suffer from dry, itchy skin and may experience other problems with their eyes, nose and sinuses.

On the other hand, if your pool is too alkaline (has a high pH), your pool will start to calcify. You’ll notice scale (just like a tea kettle) around the waterline of your pool. An alkaline pool will also damage the pool filter over time. Swimmers suffer similar symptoms as they do in an acidic pool.

There are other tests that your pool will need monthly. They include: total alkalinity, calcium hardness, total dissolved solids, stabilizer, and iron or copper.
