Maintaining the chemistry of your swimming pool will prevent harmful bacteria from building up and keep the pool pleasant and safe for use.
This involves the following
Test the pool water before and after making chemical adjustments.
Run the pool pump at all times if possible. Properly circulating the water is essential for maintaining the chemistry in your pool. Let the pump run continuously so the water stays clean and chemicals like chlorine are evenly dispersed.
Clean your pool at least once per week. Regularly cleaning your pool helps to remove contaminants like skin, oils, sunscreen, and hair products that disrupt the chemistry of the water. Use a net skimmer to remove bugs, leaves, and other surface debris.
Shock the pool once every week at night. To shock the pool, add 3 lb (1.4 kg) of calcium hypochlorite shock.
Ensure the alkalinity is between 80 and 120 ppm. Alkalinity buffers the pH and can prevent large increases or decreases in the acidity and basicity of the water. Test and adjust the alkalinity before adjusting the pH.
Maintain a pH level between 7.2 and 7.8. The term pH refers to how acidic or basic your pool water is.
Lower the pools PH level using muriatic acid. Find muriatic acid (AKA hydrochloric acid) at a pool supply store.
Increase the Ph with soda ash. Soda ash (AKA sodium carbonate) can easily raise the pH and total alkalinity of your pool water.
Adjust the chlorine levels if they are above or below 1-3 ppm. Chlorine is measured in parts per million, or ppm.
Use chlorine tablets to easily increase the amount of chlorine in the pool. It's much less work to use chlorine tablets or sticks rather than granular chlorine, which has to be pre-dissolved in water and added on a daily basis.
Put the chlorine tablets in a floating chlorine feeder. Read the packaging on the tablets to find out how many to use based on the existing chlorine levels in the water and the size of your pool.
Lower the chlorine levels with a chlorine neutralizer. If you add too much chlorine or shock to your pool, you can easily lower it with a chlorine neutralizer, available at pool supply stores.
Maintain cyanuric acid levels at no higher than 40 ppm. Cyanuric acid (CYA, also called isocyanuric acid) must be used in outdoor pools to keep the sun from burning off the chlorine
