There are 3 principal chemicals for lowering pH: muriatic acid, sodium bisulfate (dry acid) & CO2. If this is a commercial application then CO2 may be a viable source. The sodium bisulfate is dry acid which when mixed with water makes liquid acid but does not have the odor. Muriatic acid and sodium bisulfate both lower total alkalinity at hte same time as lowering the pH. CO2 may raise total alkalinity at the same time as lowering pH. The total alkalinity is important to have a stable pH which in turn is important to have a relatively constant pH for the proper effectiveness of the sanitizer (chlorine) Any other questions feel free to email me direct.

I am using a lot of acid in my pool?

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.


If muriatic acid is safe to pH the water in swimming pools can water that is just pH'ed with the acid be used on house plants?

If the water you are intending to use has been brought to Ph of 7.2 as is normally done in swimming pools then there is no problem at all using it to water plants. No. Do not use this acid mixed with anything to water your houseplants. Muriatic acid is extremely dangerous and is a matter between life or death Please check out the weblink at the lower left and you will see why. You can also ask an employee of a pool supply company if this is a dangerous practice or not.
