THERE'S no better place to be than your pool at the moment with the mercury rising.

With hundreds of pools in the backyards of Rockhampton residents, it's a timely reminder to pay close attention to your pool water.

And business is booming for Rockhampton Swimart, with pools being used regularly in the hotter days.

Rockhampton Swimart manager Brandt Cogill said business was seasonal, with spring and summer bringing in the customers.

"We have around 200 clients that we visit on a regular basis each month," Mr Cogill said.

He said the biggest problem this time of year was making sure that your pool didn't go green.

"Basically there's not enough sanitiser in the water and chlorine when that happens," he said.

"Make sure your pH balance is kept nice and low and you're adding (the right chemicals)."

But it's not only keeping your pool chemicals balanced; a pool can be damaged by the sunlight.

Swimart specialist Christ Fitzmaurice said we applied sunscreen to our skin to minimise UV damage from the sun, and similarly, pool sunscreen helped to reduce the impact the sun had on pool water.

In summer, the amount of direct, intense sunlight on your pool rose dramatically, Mr Fitzmaurice said.

The sun's UV rays "eat away" at the chlorine in your pool, destroying up to 30% of the chemical every hour, he said.

"Checking the sunscreen levels in the pool every month can save you heaps of money on extra chlorine," he said.
