Leisure Time Calcium Booster 32 oz

Extend the life of your spa and keep it running smoothly by maintaining calcium levels within the recommended amount of 150-400ppm. Low calcium levels in spa water can result in foaming and may also etch plaster, so it’s important to test water regularly and adjust as needed.

Calcium Booster should be used when water hardness dips below recommended levels. To decrease calcium levels, the spa will need to be drained and refilled. Calcium Booster is compatible with chlorine, bromine, ozone, and biguanide sanitizers.

Directions:

1. Determine amount of product to be added. The ideal hardness level is 150-400 ppm.
2. Turn jets ON to circulate spa water.
3. Pour required amount into the water.
4. Run filter for 1 to 2 hours.
5. Retest water to ensure proper level.
Repeat steps 1-5 until proper level is obtained

One ounce of Calcium Booster raises the calcium hardness 7 ppm in 500 gallons of water. Please refer to the product label for complete usage instructions.
