Your weekly pool maintenance regime will be determined by how often your pool is used, pool system and other environmental factors.
One of the most important factors is to maintain the water chemistry balanced. Here is a list and what you need to know to keep your pool balanced.
- Total Dissolved Solids
The recommended TDS or total dissolved solids should be less than 1500 ppm. Levels can be influenced by organic compounds from pool users to by chemicals that have been added.
If the TDS is over 1500 room it can lead to a reduced effectiveness of the chlorine and other added chemicals, resulting in cloudy water. If that is the case, the only solution is to drain some of the water and replace with fresh water or increase frequency of backwashing and/or filter cleaning.
- Stabilizer 40-80 ppm
To prevent the chlorine in your salt water pool from being lost to residual processes from the sun you must keep stabilizer levels around 40-80 ppm. A pool without stabilizer could lose up to 90%of it’s produces chlorine on a sunny day.
- Salinity 2500-4500 ppm
For a pool to function efficiently at the desired salinity level which can vary slightly with different models, it must remain between 2500 – 4500 ppm. Many chlorine generator monitor and display a reading but if they don’t you will need to test the pool’s water periodically using strips or a salt water test kit. Keep in mind, it’s crucial that not too much salt is added because the only way to lower the salinity is to add fresh water.
- pH Levels 7.2 – 7.6
To allow the chlorine to work effectively a proper pH is important. A proper pH balance allows you to remove germs and bacteria and eating a safe swimming environment. A high pH can be reduced with an acid either liquid hydrochloric acid, or a dry acid. Low pH can be increased with an Alkali such as calcium carbonate.
It’s important to add the acid or alkali to maintain yuour pool at the right pH level. Adding either the acid or alkali needs to be done slowly in increments and allow the water to circulate over at least a 4-6 hour period. After, you should retest and add if necessary. Remember its easier to add than to “take away” or balance it back.
- Total Alkalinity 80 – 120 ppm
To keep the pH stabilized and prevent it from fluctuating, a proper level of alkalinity is important. Corrosion, staining or green water can be caused by low alkalinity. High alkalinity can cause cloudy water and fluctuating pH. If the total alkalinity needs to be raised, you should use Sodium Bicarbonate. Note, it’s important do this slowly as recommended by manufacturer, it can be a very slow process.
To lower the TA, use either Hydrochloric Acid or Dry Acid by adding it to to the deepest part of your pool. This process, too, needs to be down slowly and you should wait three days before retesting and adjusting if necessary.
**If you have kept up with your weekly and monthly salt water pool check then you only need to do a few check at the end OR start of the pool season.
