Shock (Superchlorination)

You'll need to know your Combined Chlorine reading in parts per million (PPM) before you can use the Shock Calculator. We recommend shocking with either Calcium Hypochlorite (un-stabalized granular only, not tablets) or with Liquid Chlorine (Sodium Hypochlorite).

Raise Chlorine Level

You should keep your pool or spa Free Available Chlorine (FAC) level between 2.0 & 10.0 parts per million (PPM). *MN only. Consult your local codes as Chlorine limits vary state by state.

Raise Total Alkalinity

You should keep your pool or spa's Total Alkalinity at 60-180 parts per million (PPM).

Lower (Neutralize) Chlorine Level

Sometimes it becomes necessary to quickly reduce the level of chlorine in your pool or spa. One way is to add Sodium Thiosulfate to neutralize the excess chlorine.

Raise Calcium Hardness

You should keep your pool or spa's Calcium Hardness at 150-250 parts per million (PPM).

Raise Cyanuric Acid (Stabilizer) Level

Cyanuric Acid should only be used on outdoor swimming pools. It isn't necessary or recommended to use Cyanuric Acid on indoor facilities. You should keep your outdoor pool or spa's Cyanuric Acid level at 0-30 parts per million (PPM).
