WHY ARE CHEMICALS IMPORTANT IN A SPA
1. EVAPORATION:
As water evaporates, only pure water evaporates, leaving the salts, minerals, metals, and any
unused chemicals behind. Adding water adds more salts, minerals, and metals. In time, the
water can become saturated with these dissolved solids and can cause stains or scale to form
on the walls of the spa or a scale build up inside the equipment. Colored or cloudy water and
possible corrosion of plumbing and fittings may also occur.
2. HEAT:
Heat causes much quicker evaporation and also will cause minerals and metals to precipitate
out of solution.
3. AIR:
Dust and other airborne contaminants are introduced into the spa.
4. ENVIRONMENT:
The environment surrounding the spa can also impact the water quality. Items such as pollen,
grass, sand, dirt, lawn fertilizer, airborne dust, insects, leaves, and pets can all affect the
water quality of the spa.
5. BATHERS:
As the spa is used, bathers introduce contaminants to the water. Increased bather load,
length of use and frequency will increase the amounts of contaminants added in to the
water.
NOTE:
The maintenance routines set forth in this manual may need to be adjusted depending
on bather load and how much the spa is being used.
