Muriatic acid, or a dry acid is the best way to lower pH in a salt water pool. This will be an ongoing demand in a salt pool. The PH factor for Sodium Hypochlorite (the type of chlorine that the salt generator produces) is around 13, which is almost 2 times higher than where you want to keep it ( between 7.4-7.6) as long as your generator is producing chlorine you will have a great demand for acid to lower pH.
You lower Ph by adding acid. Might check with your pool supplier for which acid. Often Sodium Bromate or Muriatic acids are used, but I don't know how that would be different in a salt water pool.
I use Muratic Acid, 4 cups putting 2 cups at each end toward the middle. It's my biggest problem due to my water source. we have to add a lot of water due to high evaporation. My pool store is actually cheaper than Home Depot and Lowes for this so I buy a case of 4 gallons which goes pretty fast.
When CaOCl2 is added to H20 the chlorate ions combine with the water to produce hypoclorous acid and hydroxide ions. The pools pH is subjected to alot of different vaiables the optimum pH for pools is between 7.2-7.8 so to lower pH add HCl or NaHSO4 or to raise pH add Na2CO3 or NaHCO3.
Yes you still need to control the PH of your water weather it is a salt water pool or chlorine tablet pool. with salt water pools the chlorine produced by the chlorine generator is more dependant on a lower pH, around 7.2 to 7.6 if pH goes to high the chlorine gets locked up and cant work. you can find more detailed information on our web site at www.cristal-clear-pools.com. hope this helps you.
Yes, acid controls the pH of the pool water. The higher the pH the less effective the chlorine is and the more prone it is to scaling. The ideal pH range is 7.2-7.6.
A water solution of a basic salt has a pH greater than 7; a water solution of an acidic salt has a pH lower than 7.
It depends on the pH level in the pool and the gallons of the pools, also how many ppm you want to lower it.
I don't know. My best guess is that they would taste horrible just like saltwater from the oceans because of their extremely high salt concentration. Salt water pools are less than 1/5 the salt of the ocean. The salt content mirrors the salt content of our bodies. The taste is very mild. Chlorine levels will vary. The pH and alkalinity of the water have an effect on bather comfort.
It would probably be the smart thing to do because if you combine salt and chlorine, your pH level will be extremely low (very acidic) I have to correct the above answer:::: That answ. may be partially right in that changing the water would not hurt especially if it has been more than 5 years since the water has been changed. The latter part of the answ. is what I question. "Salt water pools" have salt added in order to make chlorine. Adding chlor. by hand at a rate of a gallon at a time has a very minute effect on the pH of the pool. If anything it may raise it but seldom lower it. Adding chlor. via the salt system should also have minimal effects since it is added continually and at steady levels. The make up of the water - either acidic or alkaline can effect the chemistry. Plaster pools have a high demand for acid since there is lime in the plaster mix. HTH will have an effect on raising your pH since it is a calcium based product. Tab chlorine on the other hand can lower your pH levels because the pH of a tab is near 2.5 or3.0 --quite on the acid side. k
You will have to add an alkaline substance in order to get the kiddie pools water back to an acceptable PH level. Calcium carbonate would work to increase the PH.

CAT Controllers actually mentions that its pH controller is for ""consumers using salt-chlorine systems" http://www.catcontrollers.com/products/cat1000.htm Yes. Many commercial pools that use salt systems also have pH/ORP controllers. ORP technology is fairly costly so using a pH only controller with a salt system would be a good lower cost solution.
pH value of distilled water would be 5,6 and 7 as interaction with the atmosphere allows carbon dioxide to dissolve into it, forming carbonic acid. salt on its own has no ph value but , when mixed in water the ph value of common salt is 7 and it is neutral.
