Tips For Pool Owners During La Nina Weather

Don’t let La Niña ruin your summer of poolside fun!

Heavy rainfall means leaves, dirt and algae spores get delivered into your pool. Phosphates get deposited into the water and chlorine, salt and minerals are diluted. Combined with sunlight, these conditions are perfect for algae to grow and turn your healthy pool, into a green pool. It also affects the water’s pH, calcium hardness, total dissolved solids, alkalinity and other chemical levels.

What is La Nina?

The Bureau of Meteorology has warned to expect a La Niña weather pattern this summer, which is set to bring mass wet weather across the parts of New Zealand – with backyard pool owners warned to prepare for a whirlpool of challenges.

What are the effects of La Niña?

Typically during La Niña seasons, there is above average rainfall with extra rain, some storms and possibly even flooding expected.
Poolwerx Founder and CEO John O’Brien says the effects of this excess rain are pretty significant on your pool and could have a huge impact on backyard summer fun.

“It is pivotal for pool owners to prepare in advance, and work with their local Poolwerx team to manage these effects during and after the season, to ensure they still have a healthy pool to create backyard family memories in. The solution is simple – prepare in advance and take the necessary steps to avoid greater cost and energy to remedy the situation after summer.”

La Nina & Your Pool

The effects of this excess rain can have a significant impact on your pool’s health if you don’t look after it properly.
Along with the usual culprits that accompany heavy rain, such as debris, garden runoffs, overflow and contaminates, La Niña brings additional long-term consequences – the dilution of pool chemicals, green pools, and increased risk of mosquito-borne viruses.

Below is our easy guide for New Zealanders to help you maintain a healthy pool during stormy weather

Tips for La Nina Pool Care

Tip #1: Prepare Your Pool For Rain

Before rain hits, it’s important to balance the pool properly. Consider adding some Focus Algicide to help fight off many of the organic contaminants the rainwater introduces, making it easier to clean the pool after the rain dissipates.

Tip #2: Clean The Pool After Rain

Once the rain has passed, you can begin to clean the pool – but you’ll want to act fast, as if the pool isn’t cleaned and the chemical imbalance isn’t corrected quickly, this can damage pool equipment leading to expensive repairs.

Empty the skimmer and pump baskets and remove large debris and leaves from the water. They will influence the water chemistry of the pool and potentially stain the pool’s surface.

Tip #3: Regular Pool Water Testing

Storms and heavy rain can greatly affect the pH, water chemistry and chlorine levels of your pool. As a result, it’s recommended that you regular test your pool water after a storm or heavy rain in order to prevent an algae outbreak, brown pool or costly clean up bill.

Test & balance the pool water

Poolwerx provides water testing in-store. Take a sample of pool water to your local Poolwerx for a water test where our experts will analyse the results and recommend the best products for your pool.

Handy tip: Always take a water sample at elbow depth to get an accurate water chemistry reading – especially after heavy rain.

Tip #4: Add a Floccing Agent

Heavy rainfall can lead to water runoff into your pool containing dirt, soil and mud. If your pool is looking brown, add Focus Quick Floc
This is a fast-acting agent and perfect to use after rainstorms as it binds dirt and mud particles together to the bottom of the pool floor where they can be vacuumed.

Tip #5: Use an Algaecide

During a rainstorm, leaves, dirt and algae spores get delivered into pool water. Phosphates get deposited into the water and chlorine, salt and minerals get diluted. Combined with sunlight, these conditions are perfect for algae to grow and affect the health of a pool, leading to a green pool. In addition, if rainwater runs off the property’s roof or deck, it can also introduce foreign contaminants, alter the water’s pH, calcium hardness, total dissolved solids, alkalinity and other chemical levels.

Stop Algae Growing

Leaves, dirt and algae spores delivered into the pool water decompose, causing phosphates to be deposited into the water, which can result in a green pool once the sun comes out – and fast! Ensure you maintain correct chlorine levels as this will not only help keep your pool clean & healthy but will also help to prevent additional water usage and avoid you having to fix issues such as a ‘green pool’. If your pool has turned green after a storm, try using an algaecide, such as the Focus Algicide Concentrate to effectively kill the algae in the pool.

Tip #6: Use a Shock Treatment

Your pool water may appear cloudy as your chlorine, salt or minerals have been diluted. We recommend Focus Shock and Clear to help get your pool water sparkling again.

Prevent Cloudy Pools

Rain can dilute the chlorine, salt or minerals to where you can’t see the pool floor, but the water is a non-green colour. A quality pool clarifier or shock treatment such as Focus Shock & Clear will work to catch and group the tiny particles. This makes them easier for the filter to collect
and remove.

Tip #7: Schedule A Pool Service

After a storm it’s important to service your pool and check your equipment. By arranging for Poolwerx to service and maintain your pool, you can be assured it will be back in top condition in no time.

We All Win with Learn2Swim Poolwerx’ Learn2Swim Week returns nationwide for its eighth year 25 Sep - 3 Oct Tragically, in Australian 25 children under 5 lost their lives prematurely from drowning in Australia in the last year, a 108% increase on last year and a 9% increase on the 10-year average, with 8 of these incidents happening in swimming pools. In New Zealand, three children under the age of four lost their lives last year. This is why Poolwerx and Kids Alive are back again this year with Learn2Swim Week, offering free swimming lessons for children under five from Friday 25 September to Sunday 3 October, in an effort to reduce childhood drownings. Over the course of a week, swim schools across Australian and New Zealand will offer free swimming lessons to children under the age of five as part of the water safety initiative, with registrations still open for swim schools to sign up for the annual event. Despite water safety remaining top of mind for many families, new research from Poolwerx reveals around 15 percent of parents surveyed still know someone who had, or directly encountered, a near-drowning experience – highlighting the importance of teaching little ones basic water skills to make swimming safe and fun for parents and toddlers. Further, over 30 percent of parents whose children participated in Learn2Swim Week in 2020 enrolled their children in ongoing swim classes after the week was over2, highlighting the impact that Learn2Swim Week has on both children and the parents enrolling them. Ex-Olympian swimmer Libby Trickett, alongside former Australian Olympic swim coach and Kids Alive founder Laurie Lawrence, has partnered with Poolwerx to support the initiative, urging all parents to sign up for Learn2Swim Week this year and get their kids enrolled in lessons. Libby Trickett said, “As a mum myself, I’m really proud to be championing Learn2Swim Week for Poolwerx this year. I know just how important it is to develop swimming skills when you’re young, and really capitalise on the opportunities our beautiful climate gives us to enjoy time in the water here in Australia. Former All Blacks centre, now Crusaders and Wellington (NPC) Assistant Coach Tamati Ellison, has also partnered with Poolwerx to support the initiative, urging all parents to sign up for Learn2Swim Week this year and get their kids enrolled in lessons. “I’m really proud to be supporting Learn2Swim Week for Poolwerx this year. Growing up my siblings and I spent a lot of time around the water which helped us develop key swimming skills plus build amazing memories. Learning how to swim and feel confident in the water is important at all ages. For us Kiwis, it allows you to enjoy the New Zealand summer and keep whanau safe in and around the water,” says Tamati. “Tamaiti akoana ki Te kaukau, noho haumaru ki Te wai, Tau Ana. Okea ki a Urorotia ako ki Te kaukau I tenei rā (A person who learns to swim is safer in the water. Give it your best, learn to swim today),” he adds. Poolwerx COO Nic Brill reiterated Poolwerx’ commitment to water safety, encouraging parents to take advantage of these free classes. “Swimming is a way of life for most Kiwis and Aussies, but sadly we’re still seeing backyard drownings. That is why it is crucial to introduce kids to water safety as early as possible. As Australasia’s largest pool servicing brand, we feel that we have both an opportunity and a responsibility to promote safe water practices in our community,” Brill said. “Nearly 2.7 million Australians and 58,000 Kiwis live in a house with a swimming pool, and with people staying at home more over the last eighteen months through COVID, we know this number is rapidly increasing. That makes Learn2Swim Week an even more vital initiative, and one which we are proud to pioneer.” To locate your nearest participating swim school and sign up for a free class, visit www.learn2swimweek.com.
