Pool Care After Heavy Rain: What Every Sydney Pool Owner Needs to Know

As we’ve just experienced, Sydney’s weather can flip overnight. On Tuesday it was sunny and 27 degrees, and by Wednesday night more than 100mm of rain had poured down. One day your pool is sparkling, the next it’s taken a beating from stormwater and debris. This is where Sydney pool care after heavy rain becomes critical, because while the rain might feel refreshing, it can throw your pool’s balance completely out of whack if you don’t act quickly.

Heavy rain can:

  • Dilute your pool chemicals
  • Throw off pH and chlorine balance
  • Overwork your filter
  • Introduce leaves, dirt, and debris that encourage algae

If you don’t have a pool cleaning company looking after your pool, here are a few simple steps you can take yourself to keep it in shape after heavy rain.

3 Essential Steps to Take After Heavy Rain

1. Check and Balance Your Water Chemistry

Rainwater is often acidic and dilutes your pool chemicals. This can throw off chlorine, pH, and alkalinity levels. If you have a test kit or chemicals at home, test your water and rebalance it as soon as possible, focusing on chlorine and pH first.

2. Clear Out Debris

Leaves, sticks, and dirt not only make your pool look messy, they also use up chlorine as they break down. Scoop out debris, empty the skimmer and pump baskets, and give your pool surface a quick skim.

3. Run and Clean Your Filtration System

Storms push fine dust and particles into your pool. Run your pump for longer than usual, even overnight, to circulate the water. Clean or backwash your filter to keep it working at peak efficiency.

What If My Pool Was Just Serviced?

This is a question we get all the time at The Pool Service Co. , what should you do if a storm hits right after your technician has been? You don’t have chemicals or a test kit at home, so what’s the best move until the next visit? If you’re on a weekly service with us, here’s what to do in the meantime.

Here are the no-chemical, no-stress steps you can take:

  • Keep water moving: Run your pump longer to prevent algae from settling.
  • Remove debris quickly: Leaves and dirt are algae’s best friend, so scoop them out and empty baskets.
  • Don’t add or drain water yet: Wait for your technician to rebalance. Your pool Tech will know exactly what adjustments are needed.

By taking these simple actions, you’ll keep your pool in good shape until your next scheduled service.

Why do pools go green?

Spring is a common time for Sydney pools to turn green as warmer water increases algae growth and chemical demand while many pools are still running on winter filtration settings. Checking filtration hours, water levels, circulation and water chemistry can help prevent problems.
