TERM DEFINITION
Potential Hydro-
gen
(pH)
(Continued)
If the Tub water’s pH level is too low, the following may result:
• The sanitizer will dissipate rapidly.
• The water may become irritation to Tub users.
• The Tub’s equipment may corrode.
Low pH can be raised by adding COLDTUB Cold Water Jump Up to the Tub water.
If the pH level is too high, the following may result:
• The sanitizer is less effective.
• Scale will form on the Tub shell surface and the equipment.
• High pH will cause calcium to precipitate (fall out of suspension).
• The water may become cloudy.
High pH can be lowered by adding COLDTUB Cold Water Run Down to the Tub water.
It is important to check the pH on a regular basis. The pH will be affected by the bather load,
the addition of new water, the addition of various chemicals, and the type of
sanitizer used.
ORP Oxidation–Reduction Potential.
This is simply a measurement of the water’s ability to cleanse itself. ORP is measured in
millivolts (mV). Also refer FCL
Free Chlorine
(FCL)
FCL is the active form of chlorine that actually kills bacteria and algae (It is a Sanitizer).
Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing
unwanted organisms for growing in the Tub. At the same time, you don’t want too high a
sanitizer level, or it can irritate your skin, lungs and eyes.
Always maintain the sanitizer level in your Tub within the recommended range.
Also refer ORP
Chlorine Resid-
ual
The actual level of chlorine in the water after the chlorine demand has been satised.
Sanitizer Chemical used to kill bacteria.
Generic names: Chlorine, Bromine and Biguanide.
Warning Adding a Chlorine agent such as Cold Water Sanitizer will cause inacurate
ORP and pH readings. If chlorine is added to the Tubs water it will take three days
for the COLDTUB Pal Sensor Probe to clense itself and start sending accurate
readings to COLDTUB Pal.
Also Refer Section 1.16 Caring for your COLDTUB Pal System, Question 3 If the
COLDTUB Pal System is not working, what should I do if I need to add COLDTUB
Cold Water BOOST or other sanitizer to the Tubs water?
Parts Per Million
(ppm)
ppm: parts per million, a standard measure of chemical or mineral concentration.
Organic waste Debris such as microorganisms, perspiration, urine, etc. which needs to be burned up or
“oxidized” regularly to prevent haze, algae, chloramines, etc.
Shock An oxidizer that “burns off” the organic wastes which cause cloudiness and algae. It is a
generic term for a chemical used to oxidize organic wastes.
