Phosphates and your pool

Phosphates can be a problem all year round and slowly build up over time, however in Brisbane, August & September are when we typically see a spike in the levels of Phosphates in a lot of pools due to the Westerly winds bringing microscopic dust particles from the farms. Read on below to keep your pool water clear and algae free all year round.

What Are Phosphates

In chemistry terms, phosphate is a phosphorous molecule bound to four oxygen molecules. Phosphorous is essentially food for algae and other aquatic plants and they depend on it to grow.

The association between algae and phosphate is recognised as a major factor in the presence of algae in swimming pools despite the use of chlorine and other sanitisers.

The biggest issues for swimming pool owners from increased phosphate levels are excessive or stubborn algae blooms and rapid chlorine consumption.

How Do Phosphates Get in the Pool?

Phosphates can enter your pool a few different ways: leaves, twigs, dirt, dust and bugs blown in from the wind or washed into the pool from heavy rain along with fertilisers and pesticides used around the pool. They also come from swimmers body wastes and adding water to the pool from water tanks, these can all increase the levels of phosphates in the pool water.

For the swimming pool owner, removal of phosphates are imperative to maintain good water quality. Then, once the phosphates have been removed, it's important to maintain a low phosphate level. This will ensure clean water, better chlorine performance and no algae. All living things, including algae in swimming pools, need phosphate to survive and grow. It is common knowledge that removing the phosphate and increasing the chlorine concentration will result in less algae in the pool.

Phosphate removal is key to keeping pools algae-free, maintaining quality water and allowing other chemicals to work at their most effective level.

As additional insurance against recurring algae, a “long life” copper-based algaecide is recommended to be used in conjunction with the phosphate removal treatment. A copper-based algaecide, will maintain its efficiency over a long period of time and in doing so, assist the phosphate remover to do it"s job more resourcefully.

  1. Restrict runoff from lawns, landscaping or washing decks entering the pool

  2. Remove leaves and other debris from the pool regularly

  3. Use a long-life algaecide all year round in conjunction with their phosphate removal treatment

  4. Get Rode Pools to regularly test your pool water for phosphates and treat when necessary

We have special test kits to check the level of phosphate in swimming pools. Should the result of the test exceed the recommended level then we have Lo-Chlor Starver X to remove the excess phosphate is now readily available in store.
