Are Closing Kits Necessary?
Most pool owners are on the fence about this. Some say a pool cover is enough for the winter season, whereas others beg to differ.
While a pool cover can reduce debris or natural elements from contaminating your pool, it cannot maintain the pH value or reduce the possibility of algae growth. This is where pool kits for closing come in. Even if it is not a necessity in swimming pool maintenance, a good quality closing kit does wonders for the maintenance and longevity of your pool.
It takes some effort to use these kits on your pool in the proper manner. However, the results you will see are worth the efforts many times around.
Here are some of the benefits of using a kit:
Protecting Your Pool

Moreover, it will help reduce the chances of your pool and its equipment freezing over the winters. As a result, your pool water will remain protected, and it will be ready for you to enjoy next season.
Maintaining Pool Water Health
The kits help the pool water reach a balanced chemical level and will reduce algae growth, keeping the water healthy throughout the year.
This way, you won’t have to spend money on replacing the equipment and the water, making it simple to reopen the pool next season.
Reduced Pool Maintenance

Overall, the lifespan of your swimming pool will increase and help the pool antifreeze while ensuring the swimming pool equipment does not get damaged. However, you will still need to check on your pool periodically.
Considerations When Buying A Closing Kit
There are a lot of closing kits in the market; therefore, selecting the best for your pool can be a daunting task. Here are the elements you need to look for in a closing kit before getting it for your swimming pool.
Chemical-Free Pool Closing Shock
The best winter pool kits come with a Chlorine-Free Shock, so they do not harm the pool surfaces. It will dissolve faster and balance the pH level of your ground pool water.
Chlorine-Free Shock is an oxidizing agent that works to safeguard your pool without harming it. Moreover, the shock will not react with your pool cover and ensures maintenance of the pool with the desirable pH levels.
The pool impurities will also disintegrate as a result of using this and reduce the chances of algae growth.
Winter Floater for Your Pool
During pool closing, make sure the products you are using have the right properties. For example, your closing kit should have a Winter Floater; this will ensure there is a constant discharge of oxidizing agents. As a result, your pool water will remain healthy without the use of excessive chemicals! They have a time-release feature that ensures a periodic flow even after using your pool cover.
The chemical-free floater will ensure your pool water has proper sanitization, helping remove carbon dioxide formation and thereby reducing algae growth. These high-quality floaters will also not stain the plaster, making it discolored.
So make sure that you buy a kit containing a chlorine tablet pool floater.
It helps prevent the formation of algae and is a special form of winter pool algaecide. Furthermore, they also come in a polymer blend that creates the perfect balance in the pool winterizing kit. However, not all kits contain an algaecide.
A winterizing algaecide will ensure that there is no formation of unwanted green algae and is an important consideration while buying a pool kit for closing. It works in conjecture with the other pool closing elements to deliver a fully functional pool when you take off the pool cover.
All these products keep your pool free from damage and ensuring it lasts all winter, so when the time comes, you can open your pool cover to welcome a warm and beautiful spring.
When and How to Use a Closing Kit
How to properly close your pool? Pool closing can be difficult. However, with practice and precision, you can master it in no time. Like many of us, you can consider “Labor Day” as the unofficial pool closing season!
Depending on your location, the temperatures will drop, and you should start thinking about closing your pool for the season. This will ensure that your pool water is in good condition even after shutting it down. Your pool will be safe from damage and thus reducing your maintenance cost.
As for your concerns regarding how to use your closing kit, here are the steps.
Step 1: Add Pool Magic + PHOSfree
Do this a few weeks before your scheduled pool closing. The Pool Magic helps reduce waterline rings and any surface oils and prepares your pool surface for filtering and closing. It also helps in reducing algae growth, thus ensuring there is no odor.
Step 2: Clean the Water
Make sure to vacuum the pool. The skimming and brushing will remove debris like leaves and may also remove other sediments on the pool surface.
Step 3: Balance the Pool
Cleaning the pool will make it easier to balance it. You can test the water to ensure the pH levels are between 7.2 to 7.6 ppm. And it would be great if you ensure the alkalinity of your pool is from 80 ppm to 120 ppm as well.
However, do not change the pH levels without consulting the required range. Based on this, add balancing elements to your pool.
Step 3: Shock the Pool
Take out the equipment from the closing kit. The Chemical-Free Shock will help sanitize the pool, while the Winterizier Algaecide will prevent the growth of algae.
Look at the instructions and put in the recommended dosage of these elements. Before moving forward with your pool closing project, make sure to keep the filter pump on. It should keep the water circulated, thus making the ingredients dissolve better.
Step 4: Lower the Water Level
After shocking, you need to get the water level down by four to six inches from the skimmer. Cleaning the filter will also get rid of debris and help in achieving this.
For Above-Ground Pool Filter
Take all the removable equipment indoors. This will ensure that there is no damage from the cold and that there are no cracks in the filter.
For in-Ground Pools
It would be best if you drained the lines and plumbing and plug in with a good amount of antifreeze filling. First, however, follow the instruction manual to protect your pool lines from damage.
Do these after you have used the filter to shock the pool!
Step 5: Add the Floater And Close The Pool
Once you have completed all these steps, your pool is now ready for the final treatment. First, take the floater and poke a few holes into it, then place it in your pool. Along with this, place the winter sorb in the pool to soak up oils and grime.
Step 6: Add the Pool Cover
Followed by that, you have to take a pool cover and tightly wrap it on your pool. Thus, ensuring your pool is instantly protected from any leaves and debris making its way in.
Once you are done, all you have to now do is come back every three weeks to ensure a balanced pH level.
The Bottom Line
If you’re interested in buying a closing kit, be sure to check out the list provided above. If this is your first time using a kit, read through all instructions to understand how everything works so that you close your swimming pool properly.
If this is your first time or if it has been a while since the last opened or closed your pool, you may also want to consider hiring a professional to lead the process initially and familiarize yourself with the steps.
Finally, remember that once your swimming season is over, it’s time to close up for winter so that everything will be ready and in good condition for next summer!
