Some tips about hot water

As spa pools and hot tubs contain hot water, they must be maintained efficiently. Hot water can be an ideal breeding ground for all sorts of “nasties” which can rapidly cause skin and ear infections. There is less water for each user, the water is heated and aerated, and the water turnover rate is much higher. It is most important then, that a safe level of chlorine be maintained, because hot water will make scaling occur easily. The small volume of water also allows chemicals to build up in the spa. This build-up is called total dissolved solids or T.D.S. Total dissolved solids affects the performance of chlorine and other chemicals added, so to keep the T.D.S. at an acceptable level, it is recommended that the spa be emptied at least three or four times a year. Speciality chemicals are available to inhibit foaming caused by aeration, to combat sealing on the spa surface, and to maintain the water in a sparkling condition.

For further advice on these products, consult your local pool shop. Being immersed in hot water can also have dramatic effects on people. Here are a few tips on spa usage which should be carefully adhered to:

• Elderly persons, pregnant women, and people suffering from heart disease, high or low blood pressure, or diabetes, should not use a spa without first seeking medical advice.

• Consumption of alcohol, medication, or drugs should be avoided immediately before or during, the use of a spa. • Do not use a spa alone, and do not allow children

to use the spa unless under adult supervision. • Long exposure may result in nausea, dizziness or fainting. Do not use the spa for more than 15 to 20 minutes, then cool down slowly. If you wish, you can then return for an-

other period. • Although the use of spa scents and perfumes makes the spa more pleasant to use, many people suffer from allergic skin irritations from certain perfumes. If this occurs, empty the spa,

and refrain from using the particular products in future. (All information from “So Now You Own a P 001...” published by Aqua Health, Australia, and written by Garry Adams, 1985.)
