|here's listing of commonly asked spa & hot tub water chemistry questions.
Do I need to test my hot tub water? The water looks fine.
Yes, you do
need to test the water. Ideally, if you’re using
chlorine or bromine, your tub needs to be tested DAILY.
Pristine Blue treated spas can
be tested weekly.
Q. How come I need to test my spa water?
Regular testing of
your hot tub’s water prevents problems which can cause your spa being shut
down & being unhealthy. Testing also prevents long-term problems such as
corrosion of filters & metal pool accessories & parts. Prevention of scaling
of a spa's heater is another long-term need. We didn't even talk about
odors & germs.
Q. Why is pH so important?
Your spa's pH is very important in how well your
Spa Frog or
PrisitineBlue works. When the
pH is high, the water becomes cloudy, the sanitizer (chlorine, bromine,
etc.) works less efficiently, algae & bacteria grow more quickly, scale
begins forming on metal surfaces (especially heaters). Low pH causes very
clear, but unhealthy water because the sanitizer is used up quickly; the
water becomes corrosive, eye & skin irritation are noticed. That's why pH is
Q. Why do I have to change my spa water so often?
You know what a bathtub looks like after one person, right? What if there
were several people in their with you? The big difference between a spa & a
bathtub is that a spa has a built-in filter & it's being chemically treated.
If it gets really foamy or cloudy, then
drain, clean & refill the spa.
Q. What does
“Hot water cycle” mean?
water cycle” is another term for the length of time that water remains in a
spa. The cycle is dependent on 2 factors: the size or gallons of the spa
and how often it's used. Typically a cycle lasts between 2 & 4 months.
Q. Why is the water
in my hot tub cloudy?
Cloudy water in a hot
tub or spa is caused my a lot of things & is an almost always a good sign of
other water issues. If the water is cloudy AND is "older" than 3 months,
change the water, you’ll save yourself adding unnecessary chemicals and
time. Prevention is normally the solution!
Q. Do I have to worry about Algae growth in my spa?
In most cases, “No.” Unless
you decide to completely neglect your spa or hot tub, algae growth is rarely
a problem in a properly treated spa.
Q. I get a rash on my body whenever I use my spa. What’s going on?
Skin rashes can be caused my many factors. If you have a
"hot water rash" problem, it’s probably because you’re NOT following a
proper chemical routine. “Pseudomonas aeruginosa” is a typical problem that
is prevented by proper sanitizing. A rash could also be dry, itchy skin
because of a high pH problem or high sanitizer issue that can dry out the
skin. When in doubt, check with your doctor; then drain, clean & refill the
Spa System Flush
on a regular basis to also clean out the spa’s plumbing lines which build up
a yucky film after a while. You can find out more about

Foaming usually means that the water needs to be changed. A little bit
SpaBoss Defoamer will
treat "regular" foaming & adjusting the
Calcium Hardness will help
prevent it. If your hot tub looks more like a glass of beer then CHANGE THE
Q. Why does my hot tub get a constant build-up of "goo" at the waterline?
That "goo" or "bathtub ring" is normal. Adding
SpaBoss Descummer will
greatly prevent this unsightly ring. Have spa users shower first; that will
prevent a lot "stuff" from getting in the spa.
