Just went over and told my brother, and another sister to buy the chlorine for their pools cause it may not be available later in the year,
Not sure where they live but they should probably stock up on pool water too.
They may be wise to buy their preferred shock chlorine, and have a chlorine generator installed. Then buy salt.
I just had to pay a 300% Biden Premium to buy my chlorine. I have a gunnite plaster pool and cannot go without it.
