Should I Test My Pool Water More Often

How To Test Your Pool Chemicals.

You will want to test your pool water if you have reoccurring issues like metals if you’re on well water. Even some city water municipalities can have metals, or higher than normal phosphates. Extra contaminants such as these can make it more difficult to maintain your pool water’s chemical balance. By testing more often, you’ll be keeping a closer eye on your pool water chemicals which means you’ll also be preventing damage and costly repairs down the road.

Balancing your pool is easy when you know all the right steps. If you followed along with this post, then you should now have a perfectly balanced pool.

But if youre more of a visual learner, or just want some reference material then youre in luck.

Fill out the quick form below to download a free Pool Chemical Levels Chart to use for adjusting chemical levels. With all the information you need on one page, youll save a bunch of time and balance your pool twice as fast.

Testing Your Pool Water Chemistry For Ph Levels

pH levels stand for the total acidity of pool water and are measured on a scale of 1 to 14. Your pool should be in the middle, around 7.3 to 7.7 ppmanything under 6 indicates acidity, and anything over 8 represents alkalinity. The in-between zone is considered neutral and ideal.

Low pH levels lead to:

  • Irritation of the eyes and skin
  • Pool equipment is more likely to become damaged
  • Increased risk of corrosion of ladders, rails, and other metal pool accessories
  • Parts of the pool heater are more prone to corrosion

High pH levels lead to:

  • Reduced effectiveness of free chlorine
  • Unsanitary pool conditions
  • Irritation of the eyes and skin

Checking pool and spa chemical levels is an important practice that pool owners and operators often overlook. Swimming pool chemical testing is critical because it validates water quality and determines the necessary dosages for correcting water chemistry issues.

If your water chemistry is out of balance, you can end up with corrosive or scale-forming conditions that can be very costly to correct if left unchecked for too long. In addition, accurate chemical testing is critical for the calibration of automatic pool chemical control systems.

How Often Should I Test For Salt

4 Way Liquid Swimming Pool Chemical Test Kit

To maintain the right salt level and keep your chlorine at 2 – 4 ppm, you will want to maintain your salt level between 2500 – 4500 ppm. This is the industry average, but always follow the manufacturer’s suggested salt level. Salt test strips can be found online and at your local pool store. Your pool store can also test for salt levels when you take your water sample in. It’s quick and easy for them to do.

Test strips are the go-to for most pool owners, and salt water test strips are just like regular test strips. Get a sample of pool water, dip the salt test strip into the water, remove it, then wait for about 15 – 20 seconds for the results to show.

  • When applicable, always dilute chemicals by adding to water, never the other way around unless the containers label instructs you to do so.
  • Do not mix different chemicals together.
  • Do not put spilled chemicals back into their containers.
  • Do not smoke when handling chemicals.
  • Do not expose to heat or flames.

    When To Call A Professional

    If you arent comfortable testing your pools water quality yourself, you can always hire a professional. Many businesses will allow mail-in or walk-in with a pool water sample, which they will then test.

    Alternatively, consider using a professional service for just a few key teststhe beginning, middle and end of the summer, or after an unexpected storm, for exampleand doing the rest of the tests yourself. This helps minimize any chance of an error with your home test kits and also gives you a second opinion, all while staying hassle-free and affordable.

    How To Fix High Iron Levels

    Again, because theyre both metal elements, the same remedies to fix high copper levels will also work for high iron levels.

    You can use a metal sequestrant, which wont remove the iron, but will keep it from rusting and staining your pool. Just remember sequestrant will dissipate, so adding it must become part of your regular pool maintenance.

    Also, controlling pH levels can help control iron levels, so keep a good handle on those.

    Finally, a metal trap filter or a hose filter works just as well for iron as it does for copper. So if your water has turned a yucky brown color due to high iron levels, dont worry. Its fixable.

    Gathering A Proper Water Sample

    Take samples far from your skimmer and return jets, and well below the surface . Use a clean container test container. If you are bringing the sample to a store, make sure it has a lid.

  • Hold the container in your hand like the picture above, outside of the water. Now, turn the opening down towards the bottom of the pool.
  • Push the collection container into the water, well below the surface. Keep it facing the bottom. You want air trapped inside of it at this point.
  • Turn your hand below the surface, so the air escapes, and it looks like the picture above.

    It may take up to 24 hours to balance pool chemicals properly. The time required can increase or decrease depending on factors like the size and volume of the pool, the quality and condition of the water, whether youre shocking the pool and how many adjustments need to be made using chemicals like sodium bisulfate or calcium chloride. For instance, if you raise the pools alkalinity by adding baking soda, you should wait a minimum of six hours before retesting alkalinity levels.

    How Often To Test For Copper

    While its ideal to conduct pool water testing for chlorine and pH levels weekly, its sufficient to test for copper once a month. Testing your water on a regular basis will keep copper levels at bay before you even see its effects. This will mean less work for you as you wont have to remove liner stains on top of addressing the copper in your water.

    In addition, because low pH levels can contribute to high copper levels, its essential to test them weekly. Keep them under control, and you may be able to avoid copper buildup altogether.

    Testing Based On Chemicals

    Maintaining the appropriate chemistry of any pool is the key to ensuring it is safe and sanitary to use. Though your testing kit may test other compounds as well, here are six important ones to pay attention to.

    • Chlorine: As the main sanitary chemical in your pool water, check the free chlorine levels at least two to three times per week. Free chlorine levels should stay around 1.0 to 3.0 parts per million .
    • pH: The recommended range for pool water pH is between 7.2 and 7.8, with the ideal being 7.4. At this level, the water stays safe for your skin and the chlorine can work effectively. Test pH levels along with chlorine levels, two to three times per week.
    • Total Alkalinity: Your pools alkalinity will closely correspond with your pools pH and helps keep your pool water anti-corrosive. Test at least once a week for an ideal range of 80 to 120 ppm, or more frequently if you make pH adjustments.
    • Calcium Hardness: Ever heard of hard water? Well, the same thing can happen to your pool if youre not careful. Aim to maintain a calcium hardness level between 175 and 225 ppm or 200 and 275 ppm . Test a minimum of once a month.
    • Total Dissolved Solids: Included in this category are substances like pollen, sunscreen and dust. Test at least once a month for a maximum range of 1,500 to 2,000 ppm.
    • Metals : Test if you see staining in your pool or if you suspect the water has been exposed to metals. Otherwise, test every three to four months minimum for an ideal 0 ppm.

    How To Fix High Copper Levels In Your Pool Water

    If your pool water tests positive for copper, there are some things you can do to combat any issues that may arise.

    Metal Sequestrant

    This is by far the easiest and probably the most effective way of combating high copper levels in your pool water. Metal sequestering agents for pools are metal chelators that are added to the water that protect the metals from oxidizing on the pool surface. This is only temporary as metal sequestrants do not actually remove metals from the water. They lose their efficacy over time and get filtered and backwashed out. You will want to dose your pool per the directions on the bottle and when your pool needs it.

    Metal Filter or Trap

    I’m a member of 5 professional pool industry groups on Facebook and many pool experts swear by a product called CuLator. It comes as a monthly maintenance kit that helps eliminate metals from your pool water. You add one monthly dose to your pool and it helps eliminate metals and prevents stains on your pool surface. It’s non-toxic, does not change the pH, and each application effectively treat up to 20,000 gallons

    All Purpose Hose Filter

    This is very similar to a filter you would install on your shower head. Using a filter hose can keep some of the copper from entering your pool.

    How To Fix High Salt Levels

    Pool Water Chemical Testing

    To prevent your chlorinator from having to work too hard to assimilate an overabundance of salt, its a good idea to reduce too-high salt levels. You can easily accomplish this by draining a few inches of water from your pool, and adding fresh water to bring the level back up.

    Retest, and continue the process until salt levels are back in the optimal range.
