It is important to ensure that your pool is clean, clear, and safe for bathing. You must shock your pool as it is the best way to get a clean and hygienic pool. The pool pump setting plays an important role during the pool shocking process.

You should keep your swimming pool pump in the right setting as this will allow you to shock your pool water efficiently. In this article, we will provide complete guidance on the perfect setting for the pool pump while shocking. You can purchase premium quality pool pumps from Poolking to enhance the process of pool water shock.


Clean Your Pool With Shocking and Set the Pool Pump Setting 

It is best to use a pool net to remove debris. You should also brush the walls with a pool brush before the shocking process. The best vacuum cleaners help to remove any remaining dust or dirt that is inside the pool. Once you have cleaned the pool, you should set the setting of the sand filter pump and DE filter. If you are using a cartridge filter, it is best to remove the filter cartridges and clean them off.


Filter Settings to Re-balance the Water

After you finish the shocking process, it is recommended to run the filter for 24 hours or until the water is clear. It is also important to retest the water again to make sure that it meets the correct balance. When the chlorine level is below 5 ppm, then the pH level will be 7.4-7.6. This indicates that you are good to swim again. When your water is safe, you can start to experiment with the pool landscaping ideas and get your garden party-ready.

Which Setting Should Pool Pump Be When Shocking?

The cycle setting is used infrequently, as it is helpful when you want to mix newly added pool chemicals. It also helps to keep the pool water moving while you are performing the filter repairs.


When To Use The Recirculate Setting On Pool Pump?

The recirculate setting is used to troubleshoot problems with the pool pump while shocking the pool. The ground pool is equipped with a pool pump filter and allows you to clean the water inside the pool. Running the filter on the recirculate setting helps with battling an algae bloom. The water will circulate in the pool normally and will bypass the filter sand.

The circulation system of your pool pump must be set up regularly if you use the pool frequently. It is also important to shock your pool once a week. You must clean and backwash your filter regularly. Running your pool pump for at least 10 hours per day will help to circulate the water. It will also keep the phosphate levels below 100 ppm.


Always Run the Pump While Shocking

If you are a pool owner, then you must install a pool pump with your pool. The easy installation process of the pool pump will allow you to install it easily. The medium size pump is ideal for most of the pools.

Make sure to always run the pump when shocking the pool and set it on the circulate setting for 24 hours. The water will turn blue or cloudy while shocking. Test the water 24 hours after shocking and start to adjust pH and alkalinity levels. The chlorine will still be elevated, over a few days, and will stabilize properly.


When Would You Use the “Recirculate” Setting on Pool Pump?

Have you checked all the settings on the multi-port valve on your pool sand filter? 7 settings include Filter, Backwash, Rinse, Waste, Recirculate, Winter & Closed. Many pool owners don’t use the Recirculate setting but it is important to use the “Recirculate” on Pool Filter.

The Recirculate setting helps to recirculate the pool water without filtering it. You can use it if your pool has gone “green” with the “algae bloom”. Circulation is required for shocking the pool but the pool pump gets packed with an extraordinary quantity of algae.


Use Recirculate Setting When Adding Flocs to Your Pool

When your pool is cloudy and you want to clear it fast, then it is best to use the circulate setting on your pool. Flocculants clump together and the microscopic solid contaminants can sink into the floor. If you don’t want clumped debris in your pool pump and don’t want it to clog, then it is best to use this setting. The recirculate mode cleans the water and evens it throughout the pool, and doesn’t let the contaminants clog up on the filter medium. In the Recirculate mode keep the chemicals circulating during shocking.
