What are Phosphates in Pools?
Phosphates are minerals that pose significant challenges in pool maintenance, primarily contributing to algae growth and increased chlorine consumption.
They enter pools through various sources such as garden products, plant debris, rainwater, and residues like skin cells, body oils, soaps, and hair treatments. This influx occurs via windblown debris, sprinkler runoff, and organic matter like leaves and bark.
Why Phosphates are Bad for Pools
In pool environments, phosphates serve as a nutrient for algae, facilitating their growth even at low concentrations. This growth leads to cloudy water and a decline in water quality, making the pool less inviting and more difficult to maintain.
How Do Phosphates Occur & Appear in my Pool?!
Phosphates commonly infiltrate pools through garden products, plant debris, and rainwater. They can also originate from dead skin cells, body oils, and residues left on the skin from soaps and hair treatments.
Primary pathways for phosphates entering the pool include:
Wind carrying dirt and debris into the pool.
Sprinkler runoff from your lawn or landscaping flowing into the pool.
Organic materials such as leaves, twigs, or bark falling into the water.
How to Keep Phosphates Away from Pools
To maintain a clean and healthy pool, ongoing maintenance practices such as proper filtration, regular cleaning, and maintaining chemical balance are essential. These measures help prevent algae growth and ensure a pleasant swimming experience for pool users.
Difference Between Phosphate Remover and Algaecides
Phosphate removers and algaecides serve different purposes. A common mistake is to use a phosphate remover upon seeing a green pool or black spot algae. This approach is ineffective and wasteful.
Remember: Phosphate removers do not resolve green pools or kill algae! Phosphate removers prevent issues while algaecides treat existing algae problems. If algae is present, use algaecide. If phosphate levels are rising without visible algae, apply phosphate remover as a preventive measure.
Algae depend on phosphates as a nutrient source. Therefore, if algae are present in the pool, phosphate levels are likely low or depleted because the algae have already utilised them for growth and survival.
When Should I Use Algaecide in the Pool?
When addressing different types of algae and aiming for long-term prevention, it's crucial to use effective treatment methods.
For instance, black spot and specific types of algae cannot be effectively treated with plain chlorine or inexpensive algaecides. Such treatments may yield temporary results, but the algae is likely to reappear quickly, leading to dissatisfaction among pool users.
Copper-based algaecides are highly effective against a wide range of algae types, providing enduring protection after initial treatment. Alternatively, there are non-copper options that deliver excellent outcomes, especially when dealing with green algae.
To combat algae effectively, it's beneficial to start with a potent phosphate remover that eliminates high levels of phosphates at the outset of the treatment process. This approach helps disrupt algae's nutrient supply, contributing to more effective and lasting algae control in pools.
Step by Step for Treating Pool with Phosphate Remover
Test the pool water for phosphate levels.
Remove any debris from the pool by vacuuming before treatment.
Thoroughly backwash your pool filter.
Apply the phosphate remover according to the dosage rate on the label.
Run the pool filter continuously for 48 hours.
Perform another round of backwashing on the pool filter.
Reassess phosphate levels with another test. Repeat steps 3 to 6 if needed.
Continue Green Pool Prevention through Consistent Pool Cleaning
Regular maintenance is essential to prevent algae outbreaks and maintain pool cleanliness. Basic monthly tasks include:
Prompt removal of leaves and organic debris from the water
Regular vacuuming and cleaning of filters and pump baskets
Monitoring the phosphate levels in cleaners and pool chemicals
Preventing plant and lawn runoff from entering the pool
