How to Prepare Your Pool for Winter

When summer ends and the cold months set in, it’s the best time to clean your pool. That said, you need to get the timing right, as starting too early might cause some issues. Specifically, it’s best to begin winterising when it’s cold enough such that algae don’t grow inside your pool.

Below are several steps to follow when preparing your pool for winter.

Remove All Equipment

The first step involves removing all swimming pool accessories and equipment. These include cleaners, ladders, covers, steps, and skimmer baskets. Once they’re outside the water, clean and dry them before storing them in your garage. 

Clean Your Pool

Cleaning your pool is a vital aspect of winterisation. Start by removing any debris and leaves on the surface of the water. Thoroughly scrub the walls and the floor with a pool brush.

Suppose the water turns green and murky while scrubbing; use a stainless-steel brush to remove algae. These growths are typically found in corners, so be keen on that. Once you finish, vacuum all the dirt and confirm that your pool is spotless. 

Check Pool Chemistry

After cleaning, get a pool test kit to assess the balance of various pool chemicals. The ideal pH range is 7.2 to 7.8, and this protects your pool from corrosion and scale buildup when it’s not in use.

Alkalinity should ideally range between 100 and 150 parts per million, while chlorine levels shouldn’t exceed five parts per million. Once you attain the right balance, you’ll need to add a chemical that prevents the growth of algae. 

If you reside in a cold area, investing in a pool antifreeze is mandatory. This substance prevents the bursting and freezing of pipes caused by cold conditions.

Lower the Water Level

Another measure that protects your pool from extreme winter conditions is lowering water levels. This is especially true for people without skimmer covers and who live in regions where water freezes during winter.

Ensure that the water is at least one foot below the skimmer if you have a mesh cover. For those with solid covers, the level should be half a foot below the skimmer.

Shock Your Pool

Even if you clean your pool regularly, water gets contaminated over time.  As you swim, you litter your pool with soap residue, hair cells, and dead skin. When these contaminants combine with chlorine, your pool water becomes cloudy.

The solution to a cloudy pool is shocking. This process involves the addition of a chemical that oxidises chlorine and makes the water clean. It’s advisable to shock your pool before winter begins. However, it’s a great idea not to do it when applying an algaecide.

Cover the Pool

Once the water is clean, and the chemical balance is correct, it’s time to cover your pool. The two types of covers used on pools are safety covers and winter covers. Both are useful for preventing debris from littering your pool, but safety covers also protect people and pets from plunging into the pool accidentally.

Wrapping Up

When preparing your pool for winter, never drain the water. Doing so can potentially damage the structure because it relies on the constant pressure exerted by the water. Lastly, ensure that you clean the pool and its equipment and check the chemical balance before closing it off for winter.
