Troubleshooting Low Chlorine Readings in Newly Plastered Pools

Introduction

Maintaining the appropriate chlorine levels is crucial for ensuring a safe and healthy swimming environment in newly plastered pools. Low chlorine readings can indicate a problem with the pool's chemical balance or filtration system. This article will delve into the causes of low chlorine readings in new plaster pools and provide comprehensive guidance on adding liquid chlorine to effectively address this issue.

Causes of Low Chlorine Readings in New Plaster Pools

1. High pH Levels: New plaster contains calcium ions that can raise the pH of the water, making it more alkaline. Alkaline water inhibits chlorine's effectiveness, resulting in low chlorine readings.

2. Reaction with Plaster: The chemicals in liquid chlorine can react with the unhydrated plaster, reducing its chlorine content.

3. Inadequate Circulation: Poor water circulation can prevent chlorine from reaching all parts of the pool, leading to areas with lower chlorine levels.

4. Organic Contaminants: Substances such as algae, dirt, and body fluids can consume chlorine, resulting in reduced readings.

How to Add Liquid Chlorine to New Plaster Pools

Step 1: Test Water Parameters

Before adding chlorine, test the pool water to determine the current pH and chlorine levels. Aim for a pH between 7.2 and 7.6 and a free chlorine concentration of 1-3 ppm.

Step 2: Calculate Dosage

Calculate the amount of liquid chlorine needed based on the pool's volume and the desired chlorine level. Use the following formula:

Gallons of Liquid Chlorine = (Pool Volume in Gallons) x (Desired Chlorine Level in ppm - Current Chlorine Level in ppm) / 10

Step 3: Add Liquid Chlorine

Gradually add the calculated amount of liquid chlorine to the pool through the skimmer or directly into the water. Avoid pouring it directly onto the plaster surface.

Step 4: Monitor Chlorine Levels

Retest the chlorine levels after 30 minutes to ensure the desired concentration has been achieved. If the readings are still low, repeat the process until you reach the target level.

Tips and Tricks:

• Use a chlorine stabilizer to prevent chlorine from evaporating quickly in sunlight.
• Backwash the filter regularly to remove contaminants that can consume chlorine.
• Adjust the pH before adding chlorine for optimal effectiveness.
• Avoid using too much chlorine, as this can irritate skin and eyes.

Pros and Cons of Adding Liquid Chlorine

Pros:

• Fast-acting and effective in raising chlorine levels.
• Easy to apply and measure.
• Inexpensive compared to other chlorine sources.

Cons:

• Can react with plaster, potentially reducing chlorine content.
• Can be corrosive to pool equipment if not handled properly.
• Requires frequent additions to maintain chlorine levels.

Frequently Asked Questions (FAQs)

1. Why is the chlorine level in my new plaster pool low?

• High pH, reaction with plaster, inadequate circulation, or organic contaminants can all contribute to low chlorine readings in new plaster pools.

2. How often should I add liquid chlorine to my new plaster pool?

• The frequency of chlorine additions depends on the pool's usage and water temperature. Typically, 1-3 times per week is sufficient.

3. Can I use granular chlorine instead of liquid chlorine?

• Yes, granular chlorine can also be used in new plaster pools. However, it takes longer to dissolve and can leave a residue on the plaster surface.

4. What should I do if my chlorine level is too high?

• In case of high chlorine levels, stop adding chlorine and allow it to dissipate naturally. You can also add fresh water to dilute the excess chlorine.

5. How can I improve water circulation in my pool?

• Ensure the pump and filter are properly sized for the pool. Regularly clean the filter and check for clogged pipes.

6. Is it safe to swim in a pool with low chlorine levels?

• It is not safe to swim in a pool with low chlorine levels, as it can lead to the growth of bacteria and other microorganisms that can cause infections.

Humorous Stories and Lessons Learned

Story 1:

One sunny afternoon, a group of friends decided to go for a swim in their newly plastered pool. After a few hours of splashing and playing, they noticed that the water felt slimy and their eyes were stinging. Upon testing the chlorine level, they realized it was dangerously low. Panic ensued as they frantically tried to figure out why the chlorine had disappeared.

Lesson Learned: Regularly monitor chlorine levels in new plaster pools and address any problems promptly.

Story 2:

Another homeowner, eager to keep her pool sparkling clean, decided to add an excessive amount of liquid chlorine to her pool. Within minutes, the water turned a vivid shade of green, with a strong odor reminiscent of a chemical factory. Her well-intentioned attempt had backfired, creating a swimming hazard that required immediate remediation.

Lesson Learned: Follow the recommended chlorine dosage guidelines and avoid adding too much chlorine, which can irritate skin and cause pool damage.

Story 3:

A group of children were playing in a pool when they noticed a strange floating object in the skimmer. Curiosity got the better of them, and they pulled it out, expecting to find a toy. To their surprise, it was a bottle of concentrated liquid chlorine that had accidentally dropped into the pool. Chaos erupted as the children realized their mistake, leading to a frantic evacuation and a frantic call to the local pool service.

Lesson Learned: Always keep chemicals out of the reach of children and handle them with extreme care to prevent accidents.
