WHY ARE CHEMICALS IMPORTANT IN A SWIM 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 swim 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 swim spa.
4. Environment:
The environment surrounding the swim 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 swim spa.
5. Bathers:
As the swim 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.
Remember:
The maintenance routines set forth in this manual may need to be adjusted depending on bather
load and how much the swim spa is being used.
