When you think of pool maintenance, your mind probably jumps to skimmers, filters, chlorine levels, and robotic cleaners. But what if we told you that a humble tennis ball could also play a role in keeping your pool water clearer, your equipment healthier, and your costs down?

At The Pool Service Co., we’ve seen firsthand how this simple hack can make a noticeable difference, especially for busy pools across Sydney’s Eastern Suburbs and Northern Beaches.

  • Sunscreen, Oils, and the Hidden Pool Problem

We all know the importance of sun protection, especially in Australia, where our UV index can hit extreme levels. Whether it’s at backyard pool parties in Bondi, family barbecues in Bronte, or summer laps in Lane Cove, sunscreen is non-negotiable. But here’s the catch: that same sunscreen, combined with body oils, sweat, makeup, and hair products, can wreak havoc on your pool water.

These substances float on the surface and begin to form a greasy layer, often visible after a busy day in the pool. Not only does this look unappealing, but it also puts more pressure on your filtration system, clogs skimmers, affects chemical balance, and reduces overall water clarity. In short: it costs you more in time, maintenance, and money.


Why a Tennis Ball Works

Believe it or not, the fibres on a tennis ball are incredibly effective at attracting and absorbing these oils. Just like a sponge, a clean tennis ball can float around your pool and soak up some of the surface-level grime before it ends up in your filters or affects your water chemistry.

This method isn’t a gimmick, it’s a smart complement to regular pool maintenance, especially after:

  • Children’s birthday parties where sunscreen and oils are at peak levels
  • Hot summer weekends with back-to-back swimmers
  • High-traffic pools like those common across the Northern Beaches and Eastern Suburbs


How to Use the Tennis Ball Hack

It’s as simple as tossing a clean tennis ball into your pool after a big swim day. You can also place one in your skimmer basket for more passive, ongoing cleaning. If it starts to look grubby, just replace it or throw it in the wash (without detergent).

Pro tip: Keep a few on hand and rotate them to always have one working in the pool. Avoid using tennis balls that have been used by pets or rolled through the garden, clean and dry is best.


Real Results from a Real Solution

Using a tennis ball won’t replace your filter or skimmer, but it does reduce the load on them. This means:

  • Less work for your equipment
  • Longer filter life
  • Better chemical stability
  • Clearer water
  • Reduced maintenance costs

Our clients in the Eastern Suburbs and Northern Beaches have told us how surprised they were to see their pool looking better the next morning after tossing in a tennis ball post-party. It’s a little trick, but in pool care, small things add up.
