The 7 Best Salt Water Pool Shock to Purchase

outdoor residential pool clean fancy

Pool shock is an important chemical solution that’s necessary for the treatment of pool water. This type of treatment adds an oxidant to the water that’s able to eliminate electrons that are found in such contaminants as algae and bacteria. When you want to purify and disinfect your pool water, shocking it is an effective option. The three different types of chemicals that can be used to shock a pool include:

  • Potassium monopersulfate
  • Calcium hypochlorite
  • Sodium di-chlor

While each substance is effective at cleaning and disinfecting pool water, calcium hypochlorite is considered to be the more powerful pool shock solution. No matter which product you select, shocking your pool is a great way to get rid of contaminants and keep your water clear. An abundance of algae or other contaminants in the water heightens the likelihood that the water will become cloudy. Eventually, anyone who swims in the pool will be at risk of becoming sick.

While each pool shock product differs, it’s recommended that you shock your pool water every week or so if you want to keep the water clean and healthy. If you have a saltwater pool, not all pool shocks will be effective at cleaning your water.

Considerations for the Best Salt Water Pool Shock

When you’re searching for the right pool shock product to pair with your pool, there are several factors that you should consider, the primary of which is whether or not the product will effectively clean a saltwater pool. Since not all shock products are ideal for saltwater pools, it may take some time to find the right solution. If you want a product that will kill all bacteria, algae, and other organic contaminants, you should determine if you want the product to use chlorine or not.

While chlorine-based products are typically most effective, many pool owners prefer pool shocks that contain very little or no chlorine. If you find that you don’t like the chlorine smell, there are some pool shock products that are able to get rid of this smell, which should help you feel more comfortable when swimming in your pool. All of the pool shock products in this guide have proven to be popular and effective, which means that the one you choose largely comes down to which feature-set you prefer.

It’s important to choose the best pool shock if you want yourself and anyone else who swims in the pool to remain healthy while having a great swimming experience. If too many contaminants are left in your pool water, the water itself can become cloudy and unhealthy, which can be a hassle to deal with. Using the right pool shock treatment can eliminate all contaminants while also preventing future algae growth.

Sensorex Products

At Sensorex, we offer a range of products that you can use to test and measure the quality of your water. For instance, our pH sensors can determine if the water has become too acidic. If it has, there may be too many contaminants in the water. The ORP sensors that we offer are also able to measure how clean the water is by identifying the number of contaminants that can be found in the pool water. These measurements can be used to identify if your pool water is clean.

In the event that the water is contaminated, additional measurements can be made once you sanitize and disinfect the pool with one of the shock products mentioned previously. Our top pH sensor is the pH1000 sensor, which is ideal for simple measurements of pool water. If you would prefer to use an ORP sensor, consider using the SD7000CD-ORP sensor.
