Acid reduces Ph So by adding potash you will neutralise the acid and regain the correct Ph
Muriatic Acid
Any time you like.
That Acid is called Muriatic Acid. You put it in your swimming pool to lower the PH of the water. At lower PH Levels, the chlorine you use to sanitize the pool is more active, as a disinfectant. You MUST be careful not to put too MUCH Muriatic Acid in your pool! PH that is too low will create potentially deadly fumes, so test your water. Low pH is corrosive to plaster and metal pool parst.
Muriatic acid
only about an hour if you are using baquacil
yes but i recommend having your water tested by a professional first. They will tell you how much acid to add to your pool and the steps to take afterward. Most pool places test water free of charge.
You can get in imediately without worrying about hurting your self.
suck all the water out and keep it out for 24 hrs and put new water in
Any iron in a swimming pool is likely to cause staining. Visit your local pool store and have it tested and based on the results of the test they can provide a sequestering agent to help remove the iron.
You could add it back to the pool, if you need to lower the pH - but why put all the gunk the cell has taken from the water, back into the water? Better to discard the cell cleaning acid and use fresh acid to lower pH.
A pool supply shop. Or from a pool supply shop online. Pool Tool in Ventura CA makes these but does not sell retail. However, they may be able to direct you if your local pool store cannot order one for you. k
