| *Note
1: Soda ash (sodium carbonate) systems and sodium
hydroxide injection systems will raise the pH based on the amount
of the chemcial that is being injected. The higher the rate, and the
greater the quantity of the soda ash or sodium hydroxide is being
added to the water, the higher the pH will become. If too much of
the chemicals are added, particularly sodium hydroxide, the pH level
may raise to high, to dangerous levels. |

Question: How much harder in calcium hardness will my water be after
the neutralizer? Will I notice a difference?
Answer: The neutralizer works by adding calcium carbonate (also called
'water hardness') to the water. This raises the pH of the water from
an acidic condition (less than 7.0, which is neutral pH) to neutral
or greater than neutral. Depending on your pH to begin with, and how
much hardness and alkalinity is in the untreated water, the water
hardness will typically raise from 1 to 4 grains per gallon, or 17
to around 70 milligrams per liter of water. If there is less than
5.5 and you have very low hardness already (less than 50 mg/L) a water
softener may be required after the neutralizer. This can always be
added later, should a water softener be desired. |
