Why Chemicals Are Important - Master Spas Trainer 12 Owner's Manual

WHY CHEMICALS ARE 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 airborne dirt particles 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.
Remember:
The maintenance routines set forth in this manual may need to be adjusted depending on how much
the swim spa is being used.
