If you have a high pH, this
means that the water is alkalinic and that
you need to add muriatic acid. The pool
store will always let you know how much acid if
any is needed to add to the pool.
Always add the muriatic to the water; never add
water to the acid!!
Generally add 2 cups at a time.
This is also what is used to
clean the Turbo Cells. You place the cap
on one end of the turbo cell, fill 1/2 of the
cell with pool water, then add acid. Let
sit for 45 minutes to clean it.
Remember, this acid can burn, so don't let it
get on your skin or clothes.
