What Chemicals Do I Need for Pool Closing?

As the warm summer days fade and the leaves begin to fall, it’s time to think about closing up your swimming pool for the winter. Properly winterizing your pool with the proper pool closing chemicals is essential to ensure it remains in good condition and is ready for use when the temperatures rise again.

To accomplish this, you’ll need a variety of pool-closing chemicals.

In this essential pool closing chemicals guide, we’ll explore what’s required for a successful pool closing and introduce you to True Blue Pools, a trusted pool supply store with two locations in Kentucky to help you with all your pool maintenance needs.

Preparing Your Pool for Winter: Essential Pool Closing Chemicals

Winterizing Pool Closing Chemicals

Winterizing your pool is crucial in ensuring it survives the cold winter months. Winterizing pool chemicals include pool antifreeze, winter algaecide, and a winter closing kit.

Pool Antifreeze

Unlike automotive antifreeze, pool antifreeze is non-toxic and safe for your swimming pool. It is used to protect your pool’s plumbing system from freezing temperatures. True Blue Pools offers pool antifreeze that is specifically designed for this purpose.

Winter Algaecide

Preventing algae growth during the winter is essential to make the opening process in spring more manageable. Winter algaecide helps to keep your pool water crystal clear and algae-free.

Winter Closing Kit

A winter closing kit typically contains a combination of chemicals designed to stabilize the water chemistry, inhibit algae growth, and protect your pool surfaces during the off-season. These kits are essential for a hassle-free pool opening next year.

Chlorine Shock

Before closing your pool, you must use a high-quality chlorine shock treatment to shock the water. This will help eliminate any remaining contaminants in the water and ensure your pool is clean when you open it again.

True Blue Pools offers a range of GLB® products containing chlorine and GLB® Oxy-Brite, a non-chlorine shock.


Enzymes are an excellent addition to your pool-closing routine. They help break down and remove organic matter, such as leaves and debris, which can accumulate during the winter. Enzymes work effectively in maintaining water clarity and preventing unpleasant odors.


Algae can be a persistent problem, even in the colder months. Using an algaecide specifically designed for winter conditions can help ensure your pool water remains clear and algae growth-free.

The True Blue Pool retail pool stores carry algaecides to control black, green, yellow, and mustard color algae. The GLB® Algimycin® Winter is recommended to prevent algae all winter long.


An oxidizer, often a winter shock treatment, burns off any remaining organic material in the pool water. It helps maintain water quality and clarity during the winter months.

Stain and Scale Preventer

Stains and scale buildup can be a common issue in pools. Using a stain and scale preventer during pool closing can help prevent these issues and keep your pool surfaces looking pristine.

Complete Pool Chemical Kit

Consider investing in a complete pool-closing chemical kit for convenience and peace of mind. These kits are designed to contain all the necessary chemicals in one package, ensuring you have everything you need for a successful pool closing.
