Pool Closing Kit

A pool opening kit provides you with everything you need to open your pool after the winter season. But for your pool opening kit to be effective, you should have closed your pool in the right way. As for how you can ensure that you’ve closed your pool right, a pool closing kit will be able to help you.

A pool closing kit comes with everything you need in order to protect your pool and keep it free from algae during the winter.

What Is A Pool Closing Kit?

A pool closing kit provides you with everything you need to protect your pool through the winter, in one package. However, you may not need all the chemicals you get in your pool closing kit. So before you buy a pool closing kit, let’s look at what your kit will be providing you with:

Winter Algaecide

Before you cover your pool for the winter, you’ll need to add algaecide to it. This becomes even more important should the temperature in your area reach around 60 degrees Fahrenheit, when the pool cover is kept closed. If you already have a Polyquat Algaecide of 60%, then you may not need winter algaecide additionally. Consider getting a winter algaecide that isn’t copper-based, so it doesn’t stain your pool.

Winter Ball Or Pill

A winter ball will slowly end up releasing enzymes and clarifier that prevents scales from forming in your pool. It doesn’t affect your water chemistry in any other way. So if you find yourself struggling with scaling or scum lines in your fibreglass pool, then consider adding a winter ball. A winter ball is also easier to use than buying enzymes, stain removers and clarifiers separately.

Scale And Stain Preventer

There are a lot of pool closing kits that come with chemicals for removing stains, or for preventing the buildup of scales in the walls of your pool. But the best protection against stains is a good pool cover that keeps debris from falling into the pool.


Pool closing kits also come with an oxidiser. This is also known as chlorine-free shock. This kind of shock doesn’t need to be circulated and it won’t damage the pool liner or other surfaces. But if you’ve already shocked your pool water, then you won’t have to repeat the process again. Just ensure that your free chlorine as well as your total chlorine are within the right range.

Phosphate Remover

A phosphate remover starves algae by getting rid of its source of food. If you’ve already cleaned your pool, added algaecide, and have a good pool cover, then you won’t need a phosphate remover.

Absorbing Sponges

Some pool closing kits provide absorbing sponges so that the pool can be protected through the winter season. Say you’ve already cleaned your pool and checked and balanced the pool water. You should also have added an algaecide as well as a floater. If you’ve done all this, then you won’t need absorbing sponges.

Air Pillows

People who have above-ground pools should use air pillows under their pool covers. This helps in the prevention of ice damage, and also protects the walls of the pool from collapsing during winter. Should you have an inground pool installed by a Pool Builder Perth, then you won’t need air pillows.

Should You Buy A Pool Closing Kit?

If you haven’t bought anything to protect your pool through the winter, then a pool closing kit will provide you with everything you need. However, most fibreglass pool owners already have some if not all of what you’ll get in this kit, at home. Make a checklist of what you already have. If you find that you’re missing most of your pool winter protection equipment, then consider investing in a pool closing kit.

What Is A Pool Opening Kit?

Even if you have closed your pool properly for the winter, you’ll still need to prepare your pool before you can start using it when spring arrives. Before you can use your pool, you’ll need to prepare it using start-up chemicals. These chemicals will help you ensure that the water in the pool is clean.

With a pool opening kit, you can ensure that you protect yourself and other people who’ll be using your pool. This is done by ensuring that there are no harmful contaminants left in the fibreglass pool water. Opening your pool up for the new season is not a difficult process. But if you haven’t done it before, then you may not have everything you’ll need to start your pool up right.

You can find various kits for pool chemicals, ranging from kits that are basic to those that provide you with everything you could think of. Usually, these kits will contain shock that is chlorine-based. This kind of shock is the most powerful when it comes to getting rid of bacteria as well as other microorganisms that could be in your pool.

You’ll also find:

  • Products that help with prevention stains from forming
  • Algaecides
  • Clarifiers
  • More!

What’s useful is that the component chemicals that you’ll be getting, will already be measured, meant for pools of certain sizes. You’ll also find instructions on how you can open up your pool, and get it ready for the summer season.

Should You Buy A Pool Opening Kit?

If this is your first time opening your pool up for the summer, then you may not have everything you could need on hand. In this case, buying a pool opening kit provides you with everything needed to open up your pool, in the same place. But if you’ve already opened your pool for many years, and are a seasoned fibreglass pool owner, then you could already have a lot of what you’ll be getting in this kit, at home.

Before purchasing a pool opening kit, also ensure that it’s meant for a pool that is of the same size as yours. You don’t want to end up with less or more pool chemicals.


Buying a pool closing kit or a pool opening kit can be useful for people who want to buy everything they need to maintain their pool in one go. But many fibreglass pool owners will already have a lot of the chemicals that a pool closing or pool opening kit comes with. First, find out what pool chemicals you have at home. If you find that you need to buy everything again, then a pool closing or a pool opening kit can be a good investment.
