How Often To Shock Your Pool

Ask the Pool Guy – How to Add Chemicals to Your Pool

How will you know when to shock a pool? Dont wait for a bad smell or eye irritation before you shock your pool. It’s recommended that you should do a pool shock once a week. The more you use the pool, the more often you need to shock it.

Occasionally, you may need to perform an extra pool shock after:

  • Heavy pool use, like a pool party.
  • A severe rainstorm.

Testing Your Freshly Filled Pool Water

To find out the water balance of your source water, just use a pool test kit or test strips. Be sure that your kit or strips are fresh, last years supply may produce inaccurate results.

To produce the full battery of water tests , you will need a complete test kit like the Taylor Deluxe K-2005. If you prefer test strips, AquaChek Select 7-Way, and LaMotte Insta Test 6 are both complete test strips.

Taking a water sample to the pool store may not be the best option, as their system is designed to sell you chemicals, after which you will need to test the water again, and test all summer – so you may as well buy the K-2005 , or buy some fresh 6-way or 7-way test strips, which aren’t as accurate, but may be close enough.

Intex Pool Start Up Chemicals

Intex pools are small aboveground pools, but they still need startup or opening chemicals as any other pool. Perhaps you arent as concerned about staining and scaling as an inground pool owner, but you certainly want clean and clear water, without any signs of algae.

If you are starting with a freshly filled intex pool, consider screwing on a pre-filter to your garden hose before filling the pool, to remove excess solids and minerals, and reduce the workload for your pool filter.

Step 1 – Water Balance First! As usual, start by balancing pH, Alkalinity and Calcium Hardness levels to the chart above. Calcium is not as critical in a vinyl Intex pool, but maintaining a minimum level of 150 ppm is still a good idea. Your pool water pH level is best in the 7.2-7.5 range, and to hold the pH steady, the waters Alkalinity should be around 100 ppm. Intex pool chemicals startup would not be complete without cyanuric acid ), to protect your chlorine from the sun. Add 1 lb per 2500 gallons, to raise CYA levels to 40 ppm.

Step 2 Add Clarifier: Most Intex pool filter systems are decidedly small, and can use a helping hand. Swimming pool water clarifiers coagulate suspended material into larger clumps that are more easily filtered.

Step 5 Add Algaecide: Following label instructions for dosage, treat your Intex pool with a good quality pool algaecide, as a supplement to your chlorine treatment, to prevent algae growth.

Our Conclusion On The Order Of Adding Swimming Pool Chemicals

To keep a pool safe and clean, you should keep the water alkaline and calcium-hardened.

You must also make sure there is enough calcium hardness to prevent algae growth. You must also add bromine to kill bacteria, and finally, you must test the water regularly to check for chlorine concentration.

Keep your pool clean by vacuuming and keeping it skimmed regularly, and follow the correct order to adding swimming pool chemicals we overviewed above- total alkalinity, ph adjusters, calcium hardness, chlorine/sanitizer, and then cyanuric acid. Happy swimming everyone!

The Swimming Pool Cleaning Process

Pool chemicals are necessary to keep pools clean.

Sanitizers kill germs, bacteria, viruses, mold, algae, and more.

To keep a pool clean, people need to be careful about what they use to wash themselves and their families. They also need to be careful about how much they use.

Pool chemicals should be added to the pool to make sure it stays clean and safe. Algae needs to be removed to avoid staining and damage to the pool walls. Hard water requires more chemicals than soft or regular water to remove stains.

Knowing what to test for, use and how to mix them is important to keeping your pool healthy. So what is first when it comes to testing and adding pool chemicals in the correct order?

What Is Breakpoint Oxidation

To reach breakpoint oxidation, the chlorine reading must be 10 ppm over your combined chlorine reading.

Your chlorine has two readings: free chlorine and combined chlorine . Free chlorine refers to the chlorine that is free and available to kill.

NOTE: Pool shock products are made with unstabilized chlorine or no chlorine at all. They will go in, do their job, and get eaten up by the suns UV rays very fast. Thats why its important to shock your pool at night or dusk, and let it work for 8 hours throughout the night.

Adjust The Calcium Hardness

How to add chemicals to your swimming pool

Calcium can build up around the edges of your pool and will be noticeable because of discoloration. As well as making your pool look dirty, it can also cause damage to the equipment as well as the pool structure.

The best range for calcium hardness is 200-400 PPM.

  • To decrease calcium hardness, add fresh water to the pool
  • You may need to partially drain your pool and then top up with fresh water to remove calcium. Also, you should brush your pool and then vacuum it to remove excess calcium
  • To increase calcium hardness, add calcium chloride. Be sure to follow all manufacturers instructions.

    How To Shock The Pool

    Chemicals Needed for Pool Start

    When youre shocking a pool, the goal is to raise the free chlorine level of the pool water to roughly 10 times the combined chlorine level. Reaching this mark is the breakpoint chlorination.

    Shocking a pool should be done at dusk. The sun will burn off unstabilized chlorine. Shocking your pool at night makes sure the chemicals work properly.

    Here’s how to shock a pool:

    • Test the water. You will need to check the pH level in your pool. Pool test kits can measure the FC and TC of your water. To find the CC of your pool, subtract the FC from the TC. This will let you know how much chlorine you need to add to the pool.
    • Calculate the amount of shock you will need to mix. Refer to the amount indicated on the package of the shock chemical you plan to use.
    • You can add some granular pool shock to your swimming pool directly, but most varieties need to be mixed with water before use. Mix the granular pool shock with water ahead of time, if necessary. This will save you time and help prevent calculation mistakes. Pre-mix the pool shock in a five-gallon bucket.
    • Liquid pool shock is also available.
    • Ensure the pool pump is running.
    • Pour the mixture into the water, around the edges of the pool.
    • Let the pump run for about six hours or more.
    • Test the water to ensure proper chlorine levels.
    • Dont use the pool right away. Wait for the free chlorine levels to drop to 1 to 3 ppm.
    • Wear gloves and safety glasses while working with pool chemicals.

    Once Every Other Day Test The Water

    At least three times each week, test the pH level of your water. As long as you test it that often, it shouldnt go out of balance by too much.

    Depending on the Results, Use an Appropriate Treatment:

    Lets say that the pH level was higher than usual. Then, you should try to lower it. Additionally, if the pH level is lower, then you should raise it.

    Tips For Adding Start

    • Add Stain & Scale chemical first, especially for new plaster.
    • Try for amounts of start-up chemicals
    • Add one chemical at a time, using a pool brush to distribute.
    • Run filter pump while adding chemicals to circulate.
    • Re-test the pool water after 8 hours of filter run time.
    • Add chlorine shock when the sun is not directly overhead.
    • Add algaecides last, after chlorine level drops below 3 ppm.
    • See our Pool Start-Up Kits for all the chemicals needed.

    Once the pool is opened, you will need to circulate, filter, clean and treat the pool water – every day. Consistent water balance, constant chlorine levels and effective filtering is important to prevent water problems.

    And, as the water temperature and pool usage increases through the summer, you will need more hours of daily filtering, and more chlorine tablets to maintain sanitation and clarity.

    Manage Ph Levels: Add Muriatic Acid Of Soda Ash

    If youve ever swum in a pool and then your eyes or your skin burned while you were swimming or even after swimming, its probably because the pH levels were off in the pool. pH is for the comfort of the swimmer.

    In addition to this, chlorine is not as effective if the pH levels are not right. And finally, incorrect pH levels can increase pool equipment corrosion.

    You might want to test your pH after youve got your alkalinity settled so you know just what you need to do. pH ranges from 1.0 to 14.0 on the scale. The perfect range to be in is between 7.4 and 7.6.

    • To decrease pH, use sodium bisulfate or muriatic acid
    • To increase pH, use sodium carbonate or soda ash

    Halogens Bind To Free

    Measure And Adjust Calcium Hardness

    If you ever notice a while line or scaling around your pools water line, its probably calcium buildup. And how often you see it is directly related to your pools calcium hardness level.

    Ideal Calcium Hardness level: 200 400 ppm

    How to increase calcium hardness:

    To increase your pool waters calcium hardness use calcium chloride. Follow the usage instructions printed on the packaging.

    How to decrease calcium hardness

    • Partially drain your pool and refill it with fresh water.
    • Use a flocculant to collect and vacuum excess calcium.

    Sanitizer is what keeps your pool free of germs and bacteria. Without it, every pool would quickly become a breeding ground for germs.

    But luckily, we use sanitizers like chlorine to keep the water safe and healthy.

    When it comes to measuring chlorine, there are a few numbers to keep track of:

    • Free Chlorine
    • Measures the amount of unused, or available chlorine in the water
  • Total Chlorine
  • Measures the total amount of chlorine present in the water
  • To find your pools combined chlorine : subtract Total Chlorine from Free Chlorine

    Ideal levels for chlorine: 3 ppm

    Chlorine comes in a few forms:

    • Chlorine tablets
    • Salt chlorine generator

    For this step, you can save time and shock your pool now. This gives you a jump start on refreshing the water and takes care of sanitizing your pool.

    A few other pool sanitizers:


    Healthy pool bromine levels range from 3 ppm to 5 ppm


    Proper levels for biguanide: 30 to 50 ppm

    Basic Pool Chemistry 101

    Wouldnt it be great if you could just fill your pool with water, and then never worry about algae growing, or bacteria building up, or the water just becoming a gross breeding ground for all kinds of nasty contaminants and organisms? Sure, testing the water and adding pool chemicals on a regular basis might be time-consuming and tedious, but its absolutely necessary.

    A little up-front work means a lot less remediation later when your pool becomes infested with algae, or so imbalanced, the only solution is to drain it and start over. While keeping your pool clean and sanitized may not be the most fun tasks, theyre also not difficult. All it takes is a little basic pool chemistry knowledge, the right equipment and supplies, and a desire to keep your pool clean and swimmable.

    Balance Your Water Chemistry #

    Pool Chemical Guide

    The first step would be to check your pool chemistry. You can do this using a pH test strip. If you notice that your pH reading is low, add an alkaline solution like sodium bicarbonate to increase the pH. On the other hand, if you find out that you have a very high pH, add muriatic acid to balance the pool chemistry. Also, check the calcium hardness of your pool water. Use a calcium increaser to increase calcium hardness if it is too low. On the flip side, when you have low calcium hardness levels, use pure water to dilute the pool and lower the calcium hardness.

    Pool Water Chemical Levels

    For the most accurate pool water testing, we recommend a titration test kit the Taylor K-2005 is the same test kit used by pool stores.

    The ranges shown here are suitable for any pool surface or any type of pool sanitizer used.

    Adjusting to the lower end of these ranges is best under most circumstances.

    Step 2 – Add Stain & Scale and Clarifier: Before you shock the pool, which can disrupt other pool start up chemicals, add a Stain & Scale chemical to prevent staining by keeping minerals and metals locked tightly in solution. Follow up with a good pool clarifier, following label dosage information, to help your filter remove small suspended particles.

    Step 3 – Filter the Pool! Run the filter overnight or for 6-8 hours to distribute water balance chemicals, and then backwash or clean the filter as needed, and empty the pump and skimmer baskets. Run your filter 24/7 if possible, for the first few days after opening the pool from its winter slumber.

    Before adding your pool opening chemicals, test the water again to be sure your adjustments hit the mark, and all water balance levels are correct, preferably on the lower end of the ranges.

    Step 5 – Add Algaecide: The final product in our pool start up kits is the algaecide. Add your algaecide only after chlorine levels have dropped below 3 ppm, which is usually a few days after shocking the pool. High chlorine levels quickly deplete pool algaecides, or render them useless.
