Pool Chemical Conditions Calculator
Raise Total Alkalinity
You should keep your pool or spa's Total Alkalinity at 60 to 180 PPM.
Required Data Entry
The volume of water is (1 to 9,999,999 gallons)
gallons.
The current Total Alkalinity is (0 to 9,999)
PPM.
I want the Total Alkalinity to be (0 to 9,999)
PPM.
Calculated Results
I need to use Alkalinity Increaser (Sodium Bicarbonate) to correct the Total Alkalinity of the water. I need to add
pounds
Raise Calcium Hardness
You should keep your pool or spa's Calcium Hardness at 150 to 250 PPM.
Required Data Entry
The volume of water is (1 to 9,999,999 gallons)
gallons.
The water current Calcium Hardness is (0 to 9,999)
PPM.
I want the Calcium Hardness to be (0 to 9,999)
PPM.
Calculated Results
I need to use Hardness Increaser (Calcium Chloride Flake) to correct the Calcium Hardness of the water. I need to add
pounds.
Raise Cyanuric Acid (Stabilizer) Level
You should keep your outdoor pool or spa's Cyanuric Acid level at 0 to 50 PPM. It isn't necessary to add Cyanuric Acid to an indoor pool or spa.
Required Data Entry
The volume of water is (1 to 9,999,999 gallons)
gallons.
The current Cyanuric Acid level is (0 to 999)
PPM.
I want the Cyanuric Acid level to be (0 to 999)
PPM.
Calculated Results
I need to use Cyanuric Acid (Stabilizer) to correct the water CYA level. I need to add
pounds.
Raise Chlorine Level
You should keep your water source's (except for a spa) Free Available Chlorine (FAC) level between 1.0 and 3.0 parts per million (PPM) while your spa's FAC level should be generally higher, between 2.0 and 5.0 PPM. Heat and oil are the main reasons for difference.
Required Data Entry
The volume of water is (1 to 9,999,999 gallons)
gallons.
The current FAC reading is (0 to 99.9)
PPM.
I want the FAC reading to be (0 to 99.9)
PPM.
The water source uses
Liquid Chlorine (Sodium Hypochlorite) any brand that is similar
Calcium Hypochlorite (granular or PPG Accu-Tabs) any brand that is similar
Dichlor (granular) any brand that is similar
Trichlor (tablets, pucks or sticks) any brand that is similar
Calculated Results
I need to use
to correct the water FAC level. I need to add
Lower (Neutralize) Chlorine Level
Sometimes it becomes necessary to quickly reduce the level of chlorine in your water source, pool or spa, though time will do it for you. One way is to add Sodium Thiosulfate to neutralize the excess chlorine.
Required Data Entry
The volume of water is (1 to 9,999,999 gallons)
gallons.
The current Total Chlorine reading is (0 to 99.9)
PPM.
I want the Total Chlorine reading to be (0 to 99.9)
PPM.
Calculated Results
I need to use Sodium Thiosulfate to correct the water Total Chlorine level. I need to add
pounds.
Shock (Superchlorination)
You will need to know the Combined Chlorine reading in PPM before you can use the Shock Calculator. We recommend shocking with either Calcium Hypochlorite (granular only, not tablets) or with Liquid Chlorine (Sodium Hypochlorite).
Required Data Entry
The volume of water is (1 to 9,999,999 gallons)
gallons.
The current Combined Chlorine reading is (0 to 99.9)
PPM.
I use this chemical to shock the water
