Shocking Your Pool: The Safe and Effective Way

One crucial aspect of swimming pool maintenance is shocking, also known as superchlorination. But what exactly is shocking, and how do you do it safely and effectively? At Deep End Pools we are here to guide you through the shocking process, ensuring your pool stays healthy and inviting this summer. 

Why is shocking your swimming pool important? 

Think of chlorine as the pool’s soldier, constantly battling bacteria, algae, and other unwanted guests. While regular chlorine tablets or liquid chlorine keep your pool generally sanitised, swimmer contaminants like sweat, sunscreen, and body oils accumulate in the water, especially during summer. This buildup can overwhelm the chlorine's ability to fight them effectively. Shocking boosts the chlorine level to break down these chloramines and kill any lingering bacteria or algae spores. Here’s why shocking your pool is so important:

  • Bacteria and viruses: Shocking ensures a healthy swimming environment by killing harmful bacteria and viruses. 
  • Algae growth: If you notice a green tinge or algae spots, shocking can effectively eliminate them. 
  • Combined chlorine odours: The strong chlorine smell associated with pools comes from high levels of chloramine. Shocking reduces these unpleasant odours. 

Can you over-shock your pool?

While shocking is beneficial, using too much chlorine can be counterproductive. Here are some things that might happen which we recommend you try and avoid:

  • Skin and eye irritation: Excessively high chlorine levels can irritate swimmers eyes and skin, especially for those with sensitivities. 
  • Damage to pool liners and equipment: Over-chlorination can cause bleaching and deterioration of your pool liner, pipes and other equipment. 
  • Reduced chlorine efficiency: Too much chlorine can actually make it less effective. At very high levels, chlorine gases go off into the air instead of dissolving in the water. 

What happens if I put too much shock in my pool? 

Don’t panic if you suspect you’ve over-shocked your pool. Here’s what you can do: 

  • Add fresh water: Diluting the pool water with fresh water can help bring down chlorine concentration. 
  • Reduce filtration time: Shorter filtration cycles allow less chlorine to circulate, lowering levels. 
  • Test your chlorine levels: Use a pool test kit to measure your chlorine levels. 

At Deep End Pools, we offer a variety of pool shock options and can advise you on the proper amount and application method for your specific private pool. We also provide pool test kits and can help you establish a regular shocking routine to keep your pool sparkling clean and safe for worry-free swimming this summer.
