Have you recently had pool builders build your new swimming pool? Are you aware of the impacts rain water can have on your pool? If you live on the Gold Coast or Northern Rivers you will know exactly what can happen when the clouds open up and rain water fills your pool.

Rain water can rapidly adjust your pools chemical levels and changes can sometimes be noticeable straight away, however this is not always the case.

Often people don’t realise how quickly a pool can go green if it’s not tested and managed after extended periods of rain or heavy downpour. In particular rain water can be more acidic than regular tap water which in turn impacts on your swimming pool’s pH levels. With this extra rain water in your pool it can dilute the chemicals.

What should you be doing with your pool after rain? We recommend routinely adding a small amount of algaecide to your pool to fight off any contaminates that the rain water may have brought with it, or is likeley to bring with it. Remove any debris from your skimmer basket and clean your filter as this will ensure the best health of your pool water. Vacuum your swimming pool if need be and again rinse your filter. Use a water test kit and test the pool water chemistry including chlorine levels, salt, pH, alkalinity, and hardness. If you don’t have a water testing kit you can visit any local pool shop for a water test. From here top up your chemicals and away you go!

If you experience a drizzle of rain I wouldn’t worry too much. However, without a doubt look at testing your pool water and managing the chemical levels during extended rain periods or heave downpours.
