TITAN POOLS POOL OPERATOR EXAMQUESTIONS WITH CORRECT ANSWERS
Chlorine - Answer-Sodium hypochlorite is the most common disinfectant used
What level should the pH be? - Answer-Between 7.2 and 7.8
What happens at low pH and how to increase pH - Answer-Corrosion, staining, etching ;
use soda ash
What happens at high pH and how do you lower it - Answer-Scaling, cloudy water,
clogged filters ; muriatic acid
What happens at low alkalinity and how to raise it - Answer-Etching, corrosion, green
water, burning eyes, and pH bounce ; add sodium bicarbonate
What happens at high alkalinity and how to lower it - Answer-cloudy water, less efficient
chlorine, and pH being harder to adjust ; dilute the water or add muriatic acid
What is calcium hardness (CH) and what is a good range - Answer-Calcium Hardness
is a measure of calcium content in water. The normal range of CH is 200 to 400
What happens at low Calcium Hardness and how to raise it - Answer-Low Calcium
hardness can lead to corrosive water, etching, and staining ; add calcium chloride
What happens at high calcium hardness and how to lower it - Answer-corrosion,
scaling, clogged filters, reduced circulation, and irritation ; dilute the water
What is the range of Total Dissolved Solids (TDS) - Answer-Never exceed 2000 ppm
How hot can a spa be - Answer-Below 104 F
What is Saturation Index and what is the acceptable range - Answer-Saturation Index is
the measurement of the solubility of calcium carbonate in the water ; SI = pH + Tf + CF
+ Af -TDSf from -.3 to .3 0 is perfect
How to test chlorine - Answer-Fill the small end of the test tube until you reach the 9 mL
fill mark. Add 5 drops of R-0001. Add 5 drops of R-0002. Cap the test and invert it to
mix the solution. Judge the final coloring of your test against the colors and record the
value. This is your Free Chlorine. Now, add 5 drops of R-0003. Cap and invert the test.
This coloring is your Total Chlorine. Your Combined Chlorine is your Total Chlorine
minus Free Chlorine
, How to test pH - Answer-Fill the large end of the test tube up to the fill line found on the
side of the container. Add 5 drops of R-0004. Cap and invert to mix. Judge this color
against the test tube and record the value as your pH.
How to determine the amount of acid to add to a pool to lower pH - Answer-Complete all
of the steps for a normal pH reading. Add 1 drop of R-0004 into the completed pH test.
Cap and invert to mix. Check this result against the test tube and repeat this process
until the color of your pH test is at 7.6. Then, locate the chart labeled "acid demand."
Using the number of drops it took you to reach an ideal pH and the gallonage of your
pool, determine the amount of acid you must add.
How to determine the amount of soda ash to add to a pool to raise pH - Answer-
Complete all of the steps for a normal pH reading. Add 1 drop of R-0006 into the
completed pH test. Cap and invert to mix. Check this result against the test tube and
repeat this process until the color of your pH test is at 7.6. Then, locate the chart labeled
"base demand." Using the number of drops it took you to reach an ideal pH and the
gallonage of your pool, determine the amount of soda ash you must add.

What does CT Value mean - Answer-is the amount of time it takes to inactivate 99.9%
of a pathogen at 1ppm chlorine
E. Coli - Answer-bloody diarrhea and stomach cramping - CT Value of 1
Giardiasis - Answer-CT value of 45
Cryptosporidiosis - Answer-cramping, diarrhea, fatigue, and vomiting - CT value of
15,300
