Conclusion

After adding the recommended amount of each chemical to your pool, you should test the water to ensure the pH is balanced and that the chlorine and alkalinity levels are where they should be. Depending on the size of your pool and the amount of use it gets, you may need to adjust the chemicals every few days to maintain a safe and clean swimming environment.
