in.clear glossary



Total Dissolved Solids (TDS) is an expression for the combined content of all inorganic and organic substances contained in a liquid which are present in a molecular, ionized or micro-granular (colloidal sol) suspended form.



pH (potential hydrogen) is a measure of the acidity or basicity of a solution.



"Parts-per million" notation is used to denote relative proportions or a comparative ratio in a given measured quantity. The expression "1 PPM" means a given property exists at a relative proportion of one part per million parts examined, as would occur if a waterborne pollutant was present at a concentration of one-millionth of a gram per gram of sample solution.


Total Alkanility (TA)

Total Alkalinity or TA is a measure of the ability of a solution (such as water) to neutralize acids to the equivalence point of carbonate or bicarbonate.


Calcium Hardness (CH)

Calcium Hardness describes the concentration of calcium in your spa water.


Total Hardness (TH)

Total Hardness describes the concentration of calcium and magnesium in your spa water.


Organic Matter

Substances left behind by spa users such as oil, sweat and dead skin cells that serve as "food" for bacteria.


Bather Load

This term is used to describe the number of bathers using a spa, combined with the length and frequency of its usage. The higher the bath usage, the greater quantity of chemicals needs to be added to maintain the same spa water quality.
