CLOSING YOUR OWN POOL

What You Need to Know

Many people choose to close their own pool for different reasons. Whatever your reason, support you in that decision to take a DIY approach. However, there are a few things you should know before embarking on closing your own pool. 

Timing is Crucial

The timing of when you decide to close your pool is important. Close to early and you run the risk of algae as we continue to get a few more hot days from September into October. Close too late and you run the risk of freezing lines and damage to equipment.


We recommend closing late September, mid-late October for pool closing. If you are trying to keep the pool open for as long as possible to keep swimming it is imperative to watch the weather. It's best to close the pool before freezing temperatures are upon us. If we aren't experiencing freezing temperatures your pool could remain open up to Halloween. If your local temperatures typically stay below 65°F (18°C) during the off season, wait until the temperature falls below that point to close. Lower temperatures are inhospitable to algae and can help the water stay clearer longer. Leaving your pool open until the weather cools means you can easily clean, test, balance, and use your pool right up until it’s time to close.


Balance the water chemistry before closing

It may seem like extra work to balance the water in the pool before closing, but if the pool is closed clear and balanced there is a much better likelihood of opening the pool in better condition. We recommend bringing in a water sample a week prior to pool closing to make any adjustments to the water.

Closing Condition

If you close the pool in poor condition it's very likely the pool will open in poor condition



Check the condition of your cover

Make sure to check the condition of your cover prior to the day of closing to make sure there are no rips, tears, or breakage on the cover. If the cover is damaged we recommend ordering a new one prior to closing. If you know the size of the cover you need feel free to send us an email at michele@elitepoolsandspas.com with the dimensions of your cover and we can check if we have one in stock. If we do not have your size in stock we can get you a quote to order one. If you need to order a cover please let us know as soon as possible as the arrival of the cover may alter the scheduling of your closing.

Things to check depending on your type of cover

Above-Ground Covers

check condition of ratchets and cables

In-Ground Mesh Safety Covers

check anchors and straps

Auto Covers

check for any tears or damage 

check that your cover pump is working

Do I need a cover pump?

If you have a mesh safety cover you will not need a cover pump. If you have a standard above-ground cover or an auto cover it's imperative to keep the water on the cover to a minimum. We recommend purchasing a cover pump for the winter season to keep water off the cover. Too much water on the cover stresses the equipment holding the cover on. 


In above-ground covers if too much water accumulates on the cover, the weight alone can cause the cover to drop into the pool or cause the cover to tear leaving all the cover contents to pour into your pool, talk about a nightmare come spring time. 


If you have an auto cover it is absolutely necessary to have a cover pump because too much water on your cover could cause tearing or your cover to fall out of the track, the cover is meant to cover the pool not hold an entire season worth of water on top of it.

Get a Closing Kit Today

Pool closing kits are now available at our store location. We offer closing kits for up 15,000 gallon pools and kits that cover up to 30,000 gallon pools for In-Ground and Above-Grounds. 

Other Recommendations

We recommend using winter treatment in addition to your closing kit, which includes clarifier, algaecide and chlorine booster in 1. You can pick up the winter treatment at our store location along with your closing kit, just ask us for the winter treatment and we can get you what you need.


With the winter treatment you can prime your pool's water chemistry for closing as the treatment boosts chlorine effectiveness 65% to maintain more stable chlorine levels over the winter. More chlorine in the pool for the closing season means less bacteria in the pool come spring time. 


Most pools will only require the 1/2 gallon treatment at closing and then a maintenance dose every 60 days (usually in December and then again in early March). Using the winter treatment in the non-swimming season controls algae, keeps the pool clear (if it is closed clear and in optimal condition), and allows for a quicker start-up in the spring. For the average pool size one 1/2 gallon bottle is needed initially and then a 1/2 bottle is used for each maintenance dose. With these pool closing tips you can prime your pool for closing and set yourself up for a clean and easy pool opening.
