Calcium Hardness Increaser 14oz Swim N Spa 47240230

Description

Calcium Hardness increaser for hot tub spa water.

NOTE: THIS SWIM N SPA CALCIUM HARDNESS INCREASER CAN NOT BE SHIPPED TO CALIFORNIA!

ACTIVE INGREDIENT:
Calcium Chloride Compound…………………………..100%

Increases the calcium hardness of the spa water. Helps to prevent foaming and equipment corrosion. The standard range measurement of calcium salts contained in the water is recommended at 200-400 ppm.

Anything above this range could cause the water to be cloudy and/or scaling on the tub surface, equipment and piping. To increase hardness add Hardness Plus; to reduce hardness partially drain and refill spa.

Calcium hardness should be 200-400 ppm.
If too low, corrosion of metals in system will increase, and be harder to clean.
If too high _ scale formation will increase on surfaces.

Scale may also form in heater pipes and other circulating parts. Discoloration of surface
can take place. Scale tends to form more at pH above 8.0.

Swim N Spa Calcium Hardness Increaser is equivalent to Spa Breeze Hardness Plus
