Pool Shock Treatment 101: Understanding the Basics for a Crystal-Clear Pool


Whether you own a pool or you're in the business of pool care, understanding pool maintenance is crucial. One of the most misunderstood, yet critical components of pool maintenance, is the "shock treatment." Often, pool owners are apprehensive or unsure about how and when to shock their pools. This long-form guide will take you through the why, the when, and the how of pool shock treatment, equipping you with the knowledge to keep your pool pristine. We'll also explore the nuances of weather and location that push Winter Park, FL pool owners to be more attentive than most.


Why Shock Your Pool?

Shocking a pool refers to the practice of adding a large dose of oxidizing chemicals to the water to rid it of chloramines, which are the built-up, used chlorine compounds in the water that cause an unpleasant smell and can irritate skin and eyes. Chloramines are ineffective at keeping the pool clean and must be eliminated regularly for your pool to remain swimmable.

During the warmer summer months, organic matter like sweat, sunscreen, and algae can rapidly deplete chlorine levels and create an environment rich in chloramines. Shock treatment is used to combat this, effectively breaking down these compounds and sanitizing the pool.

When to Shock Your Pool

Pool professionals often recommend shocking a pool weekly, particularly during the peak swimming season, or after a heavy pool party. Signs that your pool needs shocking include:

  • Strong chlorine smell
  • Cloudy or discolored water
  • Allergies or breathing difficulties after swimming
  • Chlorine levels below 3.0 ppm

In Winter Park, FL, the pool season can be longer and more intense due to the weather, meaning pools are used more frequently, and shock treatments are required more often.

The Methods of Pool Shocking

There are different pool shock products on the market, each with its own set of instructions, strengths, and active ingredients. Common pool shock types include chlorine-based shocks, non-chlorine oxy shocks, and lithium-based shocks.

Chlorine Shock

  • Best for pools with stubborn algae or costly green pools
  • Typically a higher dose of chlorine (12% – 15%)
  • Often comes as a granular substance that dissolves quickly
  • Can be used as maintenance if you've been diligent about killing chloramines
  • Requires waiting time before swimming (24 hours or upon the chemical reaching a specific level)

Non-Chlorine Oxy Shocks

  • Ideal for regular maintenance and achieving the look and feel of 'fresh' pool water
  • Does not increase the chlorine content of the water
  • Breaks down and destroys chloramines, eliminating cloudy water
  • Often contains a minimum of 42% potassium peroxymonosulfate (MPS)
  • Allows for immediate swimming after application

Lithium-Based Shocks

  • A happy medium between chlorine and non-chlorine shocks
  • Double-duty, sanitizing and oxidizing capabilities
  • Compatible with most pool sanitation systems
  • Quick dissolving
  • No waiting time before swimming

In Winter Park, FL, with the weather's constant pressure, most pool owners opt for a non-chlorine shock to maintain pool health without the risk of chlorine levels spiking or causing any skin or eye irritations.

The Shocking Process

It's crucial to follow the manufacturer's instructions when shocking a pool to ensure safety and effectiveness. Here's a general outline of the process:

  1. Test Your Water: Always start by checking your pool's water balance using a test kit. Ensure your pH and alkalinity are in the proper range first, as shocking the pool can have a significant effect on these levels.
  2. Calculate the Correct Dose: Refer to the shock treatment's packaging for the recommended dose based on your pool size.
  3. Pre-Dissolve: For granular shocks, pre-dissolve the recommended dose in a bucket of water before adding it to the pool. This helps to prevent any potential damage to pool surfaces that can be caused by grains of undissolved shock.
  4. Apply: Apply the shock evenly over the water's surface. For the best results, apply the shock in the evening or when the sun is not directly over the pool, as UV rays can break down chlorine quickly.
  5. Wait: Give the shock time to work, usually overnight, unless you're using a non-chlorine shock that allows for immediate swimming.
  6. Retest: After the waiting period, test your water again to ensure the chlorine levels have returned to normal, and there is no detectable chloramine level.

It's important to note that shocking a pool uses a concentrated amount of chemicals, so following safety protocols, including wearing gloves and protective eyewear, is essential.

Fine-Tuning Your Shocking Routine

The frequency of shock treatments can vary depending on your pool's use and local weather. Here are a few factors that influence how often you should shock your pool:

  • Bather Load: More swimmers mean more contaminants. A heavy swim day should be followed by a shock treatment.
  • Weather: Rain can dilute pool chemicals, while warmer temperatures can accelerate the growth of algae and bacteria.
  • Chemical Usage: If you regularly use algaecide or have had to treat for persistent algae, you may need to shock more frequently.
  • Pool Covering: An uncovered pool is more susceptible to algae and bacteria, especially in Winter Park, FL's warmer climate.

By creating a pool maintenance routine that includes regular testing and shocking as needed, your pool in Winter Park, FL will be a refreshing oasis all summer long.
