Question:

how many chhlorine tablets do i use when first adding the chemicals to the pool. how much shock do i use and when after i use the chlorine tablet

Answer:

This depends on the volume, type of chlorine and the demand of the water (based on bather load, rain, etc.). It can be a bit of trial and error on how many tablets to keep in the water at a time, but you want enough to maintain a free chlorine residual of 1 to 3 ppm ideally. Test the water 2-3 times a week and adjust accordingly. Also, testing can help to indicate when to shock. When your free chlorine reads "0" or your total chlorine reads higher than free chlorine, time to shock. Typically the recommendation is once a week or every other week, again depending on usage and environmental factors.
