"How do these systems increase the pH level?"
These systems operate by passing the acidic water through either the
calcite or Corosex mediums which are dissolved into the water balancing
out the pH level.
"Why does the acid neutralizer increase hardness?"
A calcite system uses crushed and screened white marble limestone which is
dissolved in the water to neutralize acidic water. The dissolved limestone
in the water is responsible for the increase in hardness.
A Corosex system uses reactive Magnesia oxide which like calcite is
dissolved in the water.
"Ok, I tested my water and it has a pH of less then 4.3 what can I do?"
Corosex media is not recommended on waters with a pH below 4.3. There are
other methods that must be considered such as a chemical metering pump to
feed a liquid solution of soda ash or sodium hydroxide into the water system.
It would be best to contact a local water treatment company for this type of
system.
"How long should I backwash?"
You shouldn't need to backwash for more than a few minutes. When backwashing
it is best to keep the flow rate below 5 gpm.
"How often will I have to add media?"
It depends on how acidic your water is, and the amount of water that you use.
It's best to re-check your pH level once a month. When the pH level starts
to drop then it's time to add media.
"How do I adjust the neutralizer for my specific pH level?"
One of the nice features of the way they work is that there is no adjustment
necessary. Many times ones water might have a pH 5.8 and a few days later it
might be 6.5. That is one of the reasons we refuse to sell metered systems.
On our units the the more aggresive the water is, the more Calsite/Coresex
will be dissolved by the water.
"What is the recommended flow rate for acid neutralizer?"
For effective usage we recommend a flow rate of not more than 5gpm.
(The system includes a 5gpm flow regulator.)
