Adjusting Swimming Pool Chlorine

Swimming Pool Care & Chemistry



You can adjust and correct your swimming pool chlorine like an expert by understanding these maintenance tips whether you have an inground, above ground, or salt water swimming pool.

This page has the specific chart you need for a good pool shock or "super-chlorination" along with the best way to test.

It gives you the what, when, where, why, and how to test you chemicals along with a detailed Cyanuric Acid chart.

Do you have an interesting story or comment about your pool? You can go here and write about it


Cyanuric Chart

Cyanuric Acid Minimum Chlorine ppm Goal Chlorine ppm
20 1.5 2.5-3.0
30 1.5 3.5-4.0
40 2.5-3.0 4.5-5.0
50 3.5-4.0 5.5-6.0
60 4.5-5.0 6.5-7.0
70 4.5-5.0 7.5-8.0
80 5.5-6.0 8.5-9.0
90 6.5-7.0 9.5-10

By keeping an eye on your cyanuric acid level, your pool chlorine will do it's job properly and you may not need any extra swimming pool chemicals.

Be sure to get a good FAS-DPD Taylor Reagent K-2006 water testing kit. This kind of pool water testing kit does take a little getting used to but the time spent learning how to use it is well worth the effort.

More of an investment if you ask me.


When dealing with any kinds of swimming pool chemicals you need to handle them with care and respect.

  • Always take the proper precaution in dealing with swimming pool chemicals. Remember to read the manufacture’s labels.

  • Use heavy duty rubber gloves and goggles and keep all pool chemicals out of reach of children and pets.

  • Never store liquid chemicals over dry

  • Calcium Hypochlorite is easier, a bit safer, lighter in weight, easier to store, and 1 pound of granular equals 1 gallon (8lbs.) of liquid.

    The Best Swimming Pool Water Chemistry:

        

    1. What is swimming pool chlorine?
      2. Chlorine is nothing more than a sanitizer of your pool. It comes in either a granular or liquid form. If you choose, there are many non-chlorine and bromine sanitizers on the market.  

    2. When should I test my pool chlorine?
      3. Swimming pool chlorine should be tested in either late afternoon or early evening.  

    3. Where should I test my chlorine?
      4. You should test your chlorine in the deep end of the pool or at the furthest place from the swimming pool filter.  

    4. Why should I test my swimming pool chlorine?
      5. Chlorine, as the sanitizer of your pool, needs to be checked on a regular basis (at least once per week). You need to have enough chlorine in the pool to clean the water and destroy any bather waster and/or organic matter. Keeping your pool chlorine level at 1.0ppm-3.0ppm should accomplish this.  

    5. How do I test my swimming pool chlorine?
      6. You need to follow the manufacturer’s instructions if you’re using a dropper system or Test Strips. If using the dropper, simply hold the vial upside down over the water and go straight down about 1 foot. Turn the vial over and come straight back up and follow the dropper directions. If using a Test Strip, get a clean cup and do the same procedure as using a vial.  

    Once you have your water sample, dip the Test Strip into the water for the reading and compare with the accompanying chart.  And that's it.  See how simple it is? 

    Just follow these guidelines for swimming pool chlorine and you'll be the envy of the neighborhood.
