Muriatic acid is most commonly used in swimming pools to lower the swimming pools PH and to lower the pools alkalinity. You should use caution when working with muriatic aci â¦ d. Not only can it stain your clothes, pool deck, etc, but if you inhale too much it can cause tissue damage.hat's our pool, though, I would get one of the PH testing kits you can get at pretty much any pool supply store.Hope this helps!Mrs. Gregory Our pool installer told us to wait 3 hours after adding acid to the pool. We use the liquid form, so I don't know if the wait time is different for other forms.
Lowering the pH level of a swimming pool requires adding an acid to the water, usually muriatic acid or sodium bisulfate. Start by taking a reading of the pool's pH level using a test strip and drop kit. The ideal range is between 7.0 and 7.6. If the reading is above this range, add a solution of water and acid.
