What Is the Hard White Build-Up on My Chlorinator Cell?
The white build-up on your chlorinator cell is most likely calcium deposits. Calcium can dissolve in pool water and form solid deposits on the cell's surface over time, especially in areas with hard water. These deposits can reduce the effectiveness of your chlorinator and shorten its lifespan. Cleaning your chlorinator cell regularly will help prevent calcium build-up and keep your pool equipment functioning properly.
How Does It Get There?
Calcium build-up on your chlorinator cell occurs due to a chemical reaction between the calcium in your pool water and the metal plates in the cell. When pool water flows through the cell, an electric current is applied to the plates, which generates chlorine to sanitize the water. However, the electric current can also cause the calcium in the water to dissolve and form solid deposits on the cell's surface.
If your pool water has high levels of calcium or if the pH, alkalinity, or calcium hardness levels are not properly balanced, it can accelerate the formation of calcium deposits on your chlorinator cell. This is more likely to happen in areas with hard water, where the water contains high levels of minerals like calcium and magnesium. If left unaddressed, the calcium build-up can reduce the cell's efficiency and eventually cause it to malfunction.
Is It a Problem? What Does It Do?
Yes, calcium build-up on your chlorinator cell is a problem as it can reduce the efficiency and lifespan of your pool equipment. Here are some effects of calcium build-up on your chlorinator cell:
Reduced chlorine production: As the calcium deposits accumulate on the cell's surface, it reduces the contact area between the pool water and the cell's metal plates. This can decrease the cell's chlorine production, leading to inadequate pool sanitation.
Increased energy consumption: If the calcium build-up is severe, it can insulate the cell's metal plates, making it harder for the electric current to flow through them. This can cause the chlorinator to work harder and consume more energy, leading to higher electricity bills.
Shortened lifespan: Over time, the calcium build-up can corrode the metal plates and cause irreversible damage to your chlorinator cell, leading to a shorter lifespan and the need for costly repairs or replacements.
Therefore, it is important to clean your chlorinator cell regularly to prevent calcium build-up and keep your pool equipment functioning properly.
How Often Should I Need to Clean the Calcium Off the Cell?
The frequency of cleaning the calcium build-up off your chlorinator cell will depend on various factors, such as the size of your pool, the hardness of your water, and the amount of use your pool gets. In general, it is recommended to clean your chlorinator cell at least once every three to six months, or as needed based on the level of calcium build-up.
You can check the level of calcium build-up on your chlorinator cell by inspecting it regularly. If you notice any visible deposits or a decrease in chlorine production, it may be time to clean the cell. Additionally, you can check your pool's water chemistry regularly and maintain proper balance to prevent excessive calcium build-up on your pool equipment.
Regular cleaning and maintenance of your chlorinator cell can help ensure the efficient operation of your pool equipment and keep your pool water clear and safe to swim in.
How To Clean the White Calcium Deposits Off Your Chlorinator Cell
Cleaning white calcium deposits off your chlorinator cell is important to maintain the efficiency and lifespan of your pool equipment. Here are some steps to follow:
- Turn off the power to your pool equipment, including all chlorinators and pumps.
- Remove the chlorinator cell from the plumbing system.
- Using a garden hose, rinse the cell with water to remove any loose debris and build-up.
- Fill a bucket with a 50/50 mixture of water and Hydrochloric acid.
- Submerge the cell in the mixture for at least 10 minutes. Insnrg have even suggested leaving it in overnight if necessary.
- Using a soft-bristled brush, gently scrub the cell to remove any remaining deposits. Never use anything that could scratch the surface.
- Rinse the cell thoroughly with water.
- Reinstall the cell into the plumbing system.
- If you adjusted any valves, return them to the correct position.
- Turn on the power to your pool equipment.
- Check all your equipment and timers are performing correctly.
IMPORTANT: It is important to follow safety precautions when handling Hydrochloric acid. Wear protective gloves and eye protection, and work in a well-ventilated area. Keep well away from children and animals.
Precautions For Handling Acid Including What to Do If It Splashes on You
Hydrochloric acid is a strong chemical that should be handled with care to avoid injury. Here are some precautions to take when handling acid:
Wear protective clothing: Wear protective clothing, including gloves, long sleeves, and pants, to avoid skin contact with the acid.
Use protective eyewear: Wear protective eyewear, such as safety goggles or a face shield, to prevent acid splashes from getting into your eyes.
Work in a well-ventilated area: Work in a well-ventilated area to avoid inhaling acid fumes, which can be harmful to your lungs and respiratory system.
Handle acid carefully: Always add acid to water, not water to acid, to prevent splashing or violent reactions. Use a plastic or rubber container to mix the acid and water and avoid using metal containers.
Keep a neutralizer nearby: Have a neutralizing agent, such as baking soda or soda ash, nearby in case of acid spills or splashes.
If acid splashes on your skin or clothing, immediately flush the affected area with water for at least 15 minutes. Remove any contaminated clothing and seek medical attention if necessary. If acid gets in your eyes, flush them with water for at least 20 minutes and seek medical attention immediately. If you inhale acid fumes, move to an area with fresh air and seek medical attention if necessary.
Remember to always handle Hydrochloric acid with care and follow the manufacturer's instructions for safe use.
Before Carrying Out Any Maintenance
Always refer to your pool manufacturer guides, instructions and user manuals before carrying out any maintenance on your pool and/or pool equipment. As always follow common sense and all safety practices regarding water, power, gas, chemicals and equipment. Including wearing of protective equipment such as footwear, clothing, gloves, head, face and eye protection.
