Relative pH of Chemicals
|Unstabilized Granular Chlorine (HTH EXTRA)||11.5|
|Unstabilized Liquid Chlorine||12.5|
|Stabilized Granular Chlorine||6.0|
|Stabilized Chlorine Tablets||3.0|

Making Chemical Adjustments
|To Increase||To Decrease|
|Chlorine||Unstabilized Granular or Liquid Chlorine||Dilute the pool water Keep the pool surface exposed to allow burn-off|
|Alkalinity||Alkajuster||Dilute the pool water|
|pH||pH Up||pH Down|
|Calcium||HyCal||Dilute the pool water|
|Salt||Add Salt||Dilute the pool water|
|Copper/Iron||N/A||If Stain Erase does not work:|
– Dilute the pool water
– Stain and Scale Control
– Natural Chemistry Products
|Bromine||Bromine T ablets Oxidizer||Dilute the pool water|
When doing a series of adjustments, make sure to adjust pH levels first, then alkalinity.
Always add the chemical to the water, never the water to the chemical!
