As the owner of a spa, you have made an investment in relaxation and enjoyment. Water care in a spa is different from that in a swimming pool because the water temperature is higher, the bather load is heavier, and the environment is more conducive to the growth of bacteria and algae. You should follow the instructions provided by the manufacturer of the chemicals concerning the chemical balance of the water in your spa. The following is a list of general tips on the use and storage of chemicals.
Before using chemicals, READ the labels and directions carefully. Follow the instructions found on the label.
Keep all chemicals out of reach of children.
Store all chemicals in a clean, cool, dry, well-ventilated area preferably off the floor to prevent contamination from other minerals.
Always add chemicals directly to the spa or hot tub water. Broadcast chemicals across the surface of the water or dilute then pour into spa water with jets circulating.
NEVER add chemicals while people are in the spa.
Carefully clean up any spilled chemicals with large amounts of water to dilute and wash them away.
Since the chemistry of spa and hot tub water changes very quickly, test water with reliable test strips. Add the necessary chemicals according to the test results and instructions.
