Cleaning swimming pool water should not be necessary if the water is tested regularly and the filters kept clean.
Use your pool scoop to remove obvious debris like dead leaves, twigs and pieces of paper. This should be a regular routine because they can build up quickly and block your filters. Check the skimmer regularly especially if you are finding leaves and debris to remove from the pool by hand. Do not allow loose litter to accumulate on the pool surround or it will inevitably end up in the pool.
Clean your cartridge filter whenever the pressure shows too high. After switching off the system the pressure in the cartridge can be released so the cartridge can be removed safely. Carefully wash the outside of the cartridge and then soak it in a cartridge cleaning solution according to the instructions.
The condition of your water can be tested using the levels of PH, alkalinity and calcium hardness as a guide. Since these are all interdependent it is an achievement to get all the levels right together. These tests are the basis of swimming pool water maintenance.
Adding Chemicals to the Pool
You can get all the necessary chemicals from a pool supplies outlet. They will come under a trade name and always have instructions for use. Always use chemicals as instructed on the container.Always be sure the filter system is running when you add chemicals to your pool. Add the chemicals to water to form a solution or suspension before adding them to the pool to ensure quicker dispersal.
Swimming pool water testing kits are available at pool supplies outlets and should be used in accordance with the instructions that come with them. Using the test kits incorrectly will lead to false readings and could damage your pool and accessories if you take incorrect action based on the false results.
Your PH test kit should show a level between 7.2 and 7.6. If the PH level is too low add sodium bicarbonate to the pool. If it is too high add sodium bisulphate.
Ideally the alkalinity level should be between 100 and 120 parts per million. Use sodium bicarbonate to raise the level and sodium bisulfate to lower it.
Ideally the calcium hardness should be between 200 and 400 parts per million. Use calcium carbonate dehydrate to raise it and sodium hexametaphosphate to lower it.
A properly maintained pool should not need to have the water cleaned but if the need arises you should also try to discover the reason the water became dirty and try to prevent that happening again.
