Automatic Chlorinators: A Must Have for Pool Owners

Chlorine is a vital tool used by most pool owners to sanitize pool water. There are a few ways to dispense the chlorine into your pool, but an automatic chlorinator takes the hassle and headache out of handling chlorine.

An automatic chlorinator (also called a chemical feeder) is your best bet when it comes to dispensers because it offers consistent chlorine feed. The chlorine is fed into your pool plumbing after all the equipment, protecting the pump, filter and heater from corrosion.

Putting chlorine tabs directly into your skimmer basket can damage your liner as seen here.

Simply add chlorine tablets, adjust the valve and let your chlorinator do the work. Use test strips to get your chlorine levels just right.

If you have a pool heater, be sure to check your warranty’s requirements. An automatic chlorinator or salt water chlorine generator is mandatory and use of other chlorination methods may void your warranty.

Tracy’s Tip: When operating your automatic chlorinator, turn your pool pump on and turn the valve so it is fully open. Run the pump for a minute or so to remove the highly concentrated chlorine from the vessel. Then you can open the top of your chlorinator to add tablets without getting a blast of chlorine gas in your face. If you are exposed to chlorine gas, Poison Control recommends standing in a steamy shower for at least 20 minutes to get rid of the chlorine intake.

10 Pool Chemical Storage Safety Tips

Proper pool chemical storage is imperative to avoid harmful
reactions, mixing and spills. While fireworks may be part of our summer fun, properly storing your pool chemicals will help you avoid a dangerous 4th of July-like explosion due to improper chemical storage.

Don’t let this happen to you…

How to Properly Store Pool Chemicals

    1. Read Labels Carefully: If you do one thing to ensure pool chemical safety, this is it. All of the important hazards,
      storage instructions and safety information will be on each container of chemicals. Avoid scary chemical reactions by reading the fine print thoroughly on all of your pool
      chemicals.
    2. Storage Temperature:  Pool chemicals should never be stored in a location that exceeds 95° F. Find a cool and dry location to store your chemicals. If possible, avoid areas with high humidity and direct sunlight.
    3. Ventilation: Store your pool chemicals in a well-ventilated area. Many people choose to store their pool chemicals in the pump room, but if that is where you will be keeping your supplies, you will need an HVAC shutoff in case of an emergency situation.
    4. Fire Safety: Be smart about what you store with your pool chemicals. Do not store other flammable items such as gasoline or propane near your pool chemicals or machines like lawn mowers that may contain these flammables. Also, keep your storage area clear of flammable trash or debris.
    5. Keep Chemicals Dry: Store your pool chemicals on a raised, flat surface to guarantee they do not get wet. If your chemicals do get wet, they can leach noxious gases and cause corrosion. Keep your chemicals away from doors and windows in waterproof containers and be sure the lids are always tightly secured.
    6. Keep Like with Like: Some chemicals need to be stored apart from one another to avoid reactions. Avoid storing chemicals on top of each other and make sure chlorine and acids are not stored near each other. When in doubt, store all chemicals individually for optimal safety.
    7. Cleaning Your Storage Area: Be smart when using household chemicals and cleaners to tidy up your chemical storage area. The last thing you want is an unexpected chemical reaction caused by accidental mixing. Use cleaning products that are safe to use around pool chemicals.
    8. Lock Them Up: Make sure all your pool chemicals are stored in a locked location that cannot be accessed by children or pets.
    9. Protect Yourself: Wear gloves and protective eye-wear when working with pool chemicals and make sure they don’t come into contact with your hands, mouth or eyes. Wear long sleeves and shoes when working with pool chemicals to avoid any chance of skin irritation or burns. Add the pool chemicals to your water instead of adding water to your chemicals, which could splash onto your skin.
    10. Be Mindful of the Environment: Avoid chemical spills at all costs to prevent chemical burns and inhaling dangerous fumes and dust. Spilling chemicals on the pool deck or ground can contaminate groundwater and soil causing a host of other problems.

Follow the steps above to significantly reduce your risk of chemical illness or injury.

Pool Chemistry: The Balancing Act

Whether you are new to pool ownership or are just looking for a refresher course, balancing your pool chemistry doesn’t have to be a daunting task. The key to a clean and clear swimming pool is to ensure your pool water is both balanced and sanitized.

Check out our quick guide, followed by a more detailed chemistry lesson on pool water balance and sanitation.

Quick Guide

  • Total Alkalinity:
    • 80 – 150 ppm (concrete and gunite pools)
    • 100 – 150 ppm (painted, vinyl & fiberglass pools)
  • pH: 7.4 – 7.6
  • Calcium Hardness:
    • 175 – 225 ppm
    • 225 – 275 ppm (plaster pools)
  • Chlorine: 1.0 – 3.0 ppm
  • Cyanuric Acid:
    • 25 – 50 ppm
    • 50 – 80 ppm (pools using salt water Chlorine generators)
  • Total Dissolved Solids: 500 – 5000 ppm

Water Balance

Total Alkalinity (TA)

Total alkalinity refers to the quantity of alkaline material in the water (bicarbonates, carbonates and hydroxides). Ideally your swimming pool should maintain proper total alkalinity levels between 100-150 parts per million.

“Alkalinity is a pH buffer, meaning it helps to keep the pH from drastically moving up and down the pH scale by absorbing major changes to the waters before affecting the pH.”
Swim University

Adjusting your pool’s alkalinity is the first step. Alkalinity is defined as the ability of the water to resist changes in pH. It acts as a buffer to pH and makes it more stable.

Add an alkalinity increaser if your TA is too low. Add sodium bisulfate to decrease alkalinity if your TA is too high.

2. pH

The pH refers to the relative acidity of the water. Maintaining water at a pH between 7.4 and 7.6 (a little above neutral on the pH scale) is key to balancing your pool water. This pH range is most suitable for swimming because it is less irritable to the eyes and generally more comfortable for swimmers. Chlorine is also most effective in this range. If your pH is too high or too low, the chlorine isn’t able to do it’s job.

Precipitation, swimmers, and pool debris can all change your pool’s pH. Low pH means your water is acidic. High pH means your water is basic. Keep your pH balanced to avoid equipment and structural damage.

The biggest change to pH comes from products used for sanitation, like chlorine tabs. Chlorine tabs have a very low pH, often requiring you to add a pH increaser. Pools using a salt water chlorine generator (SWCG) often have a higher pH level. For this reason, you will need to add more pH decreaser or muriatic acid to a SWCG pool than you would in a traditional chlorine pool.

It is wise to keep both a bottle of pH Increaser (sodium carbonate) and pH decreaser (sodium bisulfate) on hand to deal with pH fluctuations that can frequently occur.

3. Calcium Hardness

Calcium hardness may not technically be part of balancing your water, but without paying attention to dissolved calcium levels, your water will pursue other avenues to find it. The proper calcium hardness level is between 175 – 225 ppm or 225 – 275 ppm for plaster pools.

Monitor the calcium levels in your pool to avoid damage to your pool walls and equipment. Protect your pool by adding calcium hardness to your water. Measure carefully, as too much calcium can lead to scaling (calcium carbonate depositing itself on surfaces) among other problems.

Use calcium chloride to raise the calcium hardness of your pool water. If you are experiencing high calcium hardness levels, the only remedy is to drain at least some of your pool water to dilute it with fresh water.

Cyanuric Acid (CYA)

Cyanuric acid (CYA) is a water stabilizer and should be in the range of 25-50 ppm or 50–80 ppm for salt pools. Cyanuric acid is sold as either a pool stabilizer or pool conditioner and helps prevent destruction of chlorine from the sun’s UV rays. It is especially important to add cyanuric acid if you are starting with fresh water and need a stabilizer base. Chlorine tabs already contain cyanuric acid, so CYA is replenished if you’re using tabs. With a salt water chlorine generator however, CYA will need to be added separately.

Sanitation

Sanitation is imperative to disinfecting your pool water to prevent disease spreading organisms, as well as bacteria and algae growth. Environmental pollution from humans, animals, cosmetics, leaves, pollen, dirt and other debris are constantly affecting your pool water. When it comes to pool sanitation, chlorine is the most commonly used ingredient.

Chlorine

Chlorine is used as a water sanitizer. It works by disinfecting your water to rid it of any bacteria, algae, ammonia, and other contaminates. Your chlorine levels should ideally stay between 1.0 – 3.0 ppm.

Add Chlorine to your water with tablets or use a powdered or granular chlorine (we prefer tablets for ease of use). Tabs can be added to a chlorinator, floating dispenser, or skimmer basket(s) in your pool.

“When buying chlorine make sure you look for Trichloro or Dichloro as an active ingredient. These types of chlorine products are stabilized. UV rays from the sun eat up chlorine, but if it’s stabilized, it drastically slows down this process.”
Swim University

Alternatives to Chlorine

Bromine, biguanide and the minerals silver and copper are sanitizer alternatives to chlorine. While they each have their pros and cons, chlorine remains the most popular and least expensive option. Using a mineral solution still requires small amounts of chlorine for complete sanitation. Contrary to popular belief, a SWCG creates chlorine. People often assume a salt water pool is better because it doesn’t use chlorine, but this is a misconception!

Pool Shock

Super chlorination or “shocking” is also vital to maintaining a clean and healthy pool. When you shock your pool, you are essentially adding 3x the normal amount of chlorine you would regularly add. A shock treatment will burn organic materials out of the water and allow the sanitizer to work properly.

Shock your chlorine pool when any of the following occur:

  • Your pool is cloudy.
  • There is pool algae present.
  • The water temperature exceeds 84 degrees.
  • Your chlorine level is lower than 3 ppm.

Finishing Touches

When you have added all the necessary chemicals to your pool, let your pool pump run so your chemicals can circulate throughout. Balancing your pool water may seem tricky at first, but it will get easier with practice and patience.
