Chatbot has read manual and is ready to answer your questions.
Calcium Hardness
Abbreviated as CH. Calcium hardness is a measure of the total amount of dissolved calcium in the water. Calcium helps control the
corrosive
nature of the spa’s water and is why soft water is not recommended. The low CH level can cause
corrosion
to the equipment and can cause staining of the spa shell. See page 25 for testing for and balancing calcium hardness.
Corrosion
The gradual wearing away of metal spa parts, usually caused by chemical action. Generally, corrosion is caused by low
pH
or by water with levels of
TA
,
CH
,
pH
or sanitizer which are outside the recommended ranges.
Dichlor
Monopersulphate or MPS
Oxidizer
Also called sodium dichlor. It is a type of chlorine and is frequently used when
shocking the water
. An effective
chlorine
-based powdered
oxidizer
and
sanitizer
. Dichlor works by oxidizing waste product in the water such as
bromamines
and
chloramines
and causing them to burn off.
Frequently used when
shocking the water
. An effective non-chlorine-based powdered
oxidizer
that works well with both
chlorine
and
bromine
. It works by oxidizing waste product in the water such as
bromamines
and
chloramines
and causing them to burn off.
Shocking the water
with an oxidizing chemical prevents the buildup of contaminants, maximizes
sanitizer
efficiency, minimizes combined
chlorine
and improves water clarity.
Ozone pH
Ozone is a powerful oxidizing agent which is produced in nature and artificially. Ozone forms no by-products of
chloramines
(ozone actually oxidizes chloramines) and will not alter the water’s
pH
.
The pH level is the measure of the balance between acidity and alkalinity. Low pH causes the water to be too acid, which will cause
corrosion
, whereas high pH causes the water to be too alkaline, which will cause
scaling
. See page 25 for testing for and balancing pH.
ppm
Sanitizer
Scale
The abbreviation of “parts per million”, the standard measurement of chemical concentration in water. Identical to mg/l (milligrams per liter).
Sanitizer is a chemical added to the water to kill bacteria and viruses and keep the water clean.
The two sanitizers we recommend are
chlorine
and
bromine
. See page 26 for discussion of sanitation.
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
Total Alkalinity
Trichlor
Also called shocking the water, shock treatment, or superchlorination. Shocking the water is adding significant doses of
dichlor
or
MPS
to
oxidize
non-filterable organic waste and to remove
chloramines
and
bromamines.
Shock treatment breaks down organic waste contaminants which cause odor and cloudy water. See page 27 for discussion of shocking the water.
Abbreviated as TA. Total alkalinity is the measure of the total levels of carbonates, bicarbonates, hydroxides, and other alkaline substances in the water. TA is important for
pH
control. If the TA is too low, the
pH
will fluctuate out of control, and if it is too high, the
pH
becomes difficult to stabilize. See page 24 for testing for and balancing total alkalinity.
Used as a pool
sanitizer
. NEVER use trichlor in a spa. Trichlor is extremely acidic and will lower the
pH
, causing corrosion to equipment. Using trichlor will void your warranty.
Water Testing Methods
There are two testing methods to choose from:
Test strips are a convenient testing method commonly used by spa owners.
The reagent test kit is a method which provides a high level of accuracy but is more expensive and more difficult to use.
