Shelf Life and Other Tips
Pool shock has a virtually limitless shelf life under proper conditions, which makes it a vastly superior alternative to chlorine. As you can see, it also needs much less storage space.
Although it is non-flammable, it can be corrosive and should be stored carefully away from any other corrosive or flammable products. The container of shock/water solution that you made in step two will provide you with a lot of purified water after the mixture has been filtered. If you plan to store this container with the solution in it, make sure that it is well-labeled and stored properly. As a side note, the manufacturer of pool shock has indicated that it should never be kept in an area that will exceed 95 ° Fahrenheit.
