How do you read pool water test results?
How do you read pool water test results?
Simply dip one test strip into pool or spa water at elbow’s depth and remove immediately. Shake once to remove excess water. Hold strip level and visually compare the strip to the color chart included on the bottle. Select the corresponding test result colors within 15 seconds of wetting.
What should pool water readings be?
A pool that is “balanced” has proper levels of pH, Total Alkalinity, and Calcium Hardness. These are: pH: 7.2-7.8, Total Alkalinity: 80-120 ppm, Calcium Hardness, 180-220 ppm and Cyanuric Acid (Stabilizer): 30-50 ppm. Chlorine levels should remain constant in the 1-3 ppm range.
What does my pool water test mean?
Pool-water chemical levels to test and balance. The four chemical levels critical to healthy water are free chlorine, calcium hardness, pH, and total alkalinity. If water analysis indicates that one or more chemical levels are too high or too low, the message is to take action.
What is a good chlorine level for pool?
CDC recommends pH 7.2–7.8 and a free chlorine concentration of at least 1 ppm in pools and at least 3 ppm in hot tubs/spas.
What should the pH and chlorine level be in a pool?
between 7.2 and 7.8
A good chlorine level is between 1.0 and 4.0 parts per million (ppm), while the pH should be between 7.2 and 7.8.
What should my pool hardness be?
Calcium hardness must be actively managed—along with pH and total alkalinity—to keep water in proper chemical balance. Current industry standards call for maintaining calcium hardness in the ideal range of 200–400 ppm in pools and 150–250 ppm in spas.
How do I know my pool water is safe?
As a backyard pool owner, you should check the disinfectant (chlorine or bromine) level and pH at least twice per day (and more often when the pool is in heavy use) to make sure they are correct: 1–10 parts per million (ppm) free chlorine or 3–8 ppm bromine. pH 7.2–7.8.
Is too much free chlorine bad?
But excessive exposure to chlorine can cause sickness and injuries, including rashes, coughing, nose or throat pain, eye irritation and bouts of asthma, health experts warn. Instructions for safely chlorinating a pool usually call for a maximum of four parts per million when people are in the pool.
How long does chlorine last in pool water?
Tap water chlorine dissipates almost fully in a day, but pool chlorine takes about 4 1/2 days. (Rough orders aro too many variables.) There are compounds which are considerably slowed by catalysts that make keeping a swimming pool level stable.
Will baking soda lower chlorine level in pool?
Chlorine works most efficiently in water with a neutral pH level between 7.4-7.6. If the pool is too alkaline, or more than a pH of 8.0, the efficiency is less than 20 percent. To raise your pH levels, it can be as simple as adding seven to nine pounds of baking soda to your pool water.
How do you know if you have enough chlorine in your pool?
If the chlorine smell is very strong, however, you may soon spot “red-eyed” swimmers emerging from the pool. That’s when the pool water is assumed to have “too much chlorine” in it. Ironically, a strong chemical smell around the pool and “swimmer red eye” may be signs that there is not enough chlorine in the water.
