DPD:
The preferred reagent used in test kits to measure the Free Available Chlorine.
Halogen:
Any one of these five elements: fluorine, chlorine, bromine, iodine and astatine.
MPS:
Monopersulfate is the non-chlorine oxidizer used with the FreshWater
Ag+
®
Silver Ion Purification system.
Oxidizer:
The use of an oxidizing chemical is to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize
combined chlorine and improve water clarity.
Pathogen:
A microorganism such as bacterium that cause disease.
pH:
The measure of the spa water’s acidity and alkalinity. The recommended pH for the spa water is 7.4 to 7.6. Below 7.0 (considered
neutral), the spa water is too acidic and can damage the heating system. Above 7.8, the water is too alkaline and can result in cloudy
water and scale formation on the shell and heater.
ppm:
The abbreviation of “parts per million”, the standard measurement of chemical concentration in water. Identical to mg/l
(milligrams per liter).
Reagent:
A chemical material in liquid, powder or tablet form for use in chemical testing.
Sanitizer:
Sanitizers are added and maintained at recommended residuals to protect bathers against pathogenic organisms which can
cause disease and infection in spa water.
Scale:
Rough calcium-bearing deposits that can coat spa surfaces, heaters, plumbing lines and clog filters. Generally, scaling is caused
by mineral content combined with high pH. Additionally, scale forms more readily at higher water temperatures.
Shock Treatment:
Also known as “super-chlorination” when chorine is used. Shock treatment is a process of adding significant doses
of a quick dissolving sanitizer (MPS or sodium dichlor is recommended) to oxidize non-filterable organic waste and to remove
chloramines and bromamines.
Total Alkalinity:
The amount of bicarbonates, carbonates, and hydroxides present in spa water. Proper total alkalinity is important for
pH control. If the TA is too high, the pH is difficult to adjust. If the TA is too low, the pH will be difficult to hold at the proper level. The
desired range of TA in spa water is 125 to 150 ppm.
