Understanding phosphate is key to keeping your pool running efficiently and trouble free. Phosphate is the major food source for algae growth in swimming pools. Whilst chlorine and algaecides kill or prevent algae they do not remove unwanted phosphate from the water. As algae dies it releases phosphate, unless the phosphate is removed it remains as a food source for new algae growth.
By removing phosphate and eliminating algae the demand for chlorine as a sanitiser is reduced, therefore, lowering chorine consumption and reducing costs. Following the Lo-Chlor Phosphate Protection Program is key to keeping pools algae free, maintaining maximum water quality and allowing other chemicals to work at their most effective level. Our expertise in this area has ensured that the Lo-Chlor Starver® range of products are the phosphate removers of choice across Europe.
Lo-Chlor Phosphate Protection Program Step 1
Lo-Chlor Starver® X is a CURATIVE for high phosphate levels and should be used when the level of phosphate is 2000ppb or above. This unique concentrated product is the initial shock treatment for pools. Each 1 litre dose will remove up to 6000ppb (6ppm) per 50,000 litres of water. Once shocked, lower phosphate levels can be effectively managed using Lo-Chlor Starver®.
Lo-Chlor Phosphate Protection Program Step 2
Lo-Chlor Starver® is a PREVENTATIVE and should be used ongoing as a MAINTENANCE product to keep the phosphate level as close to zero as possible. This patented product is designed for weekly use once the level is below 2000ppb (2ppm). Once below 2000ppb (2ppm) use an initial dose of 1 litre per 50,000 litres of water every 2 – 3 days. When the phosphate level has dropped to between 0-200ppb carry out weekly maintenance doses of 500ml per 50,000 litres if water.
INFORMATION ON PHOSPHATE
Where Does Phosphate Come From?
The main source of phosphate is from incoming mains water however leaves, rain, plants, grass clippings, fertilizers, bathers and poolside cleaners will all deposit phosphate into the water. Some pool chemicals also contribute to adding phosphate to the pool. In most cases the presence of phosphate indicates this will be an ongoing problem therefore it makes sense to carry out weekly maintenance doses of Starver®.
What Problems Can Phosphate Cause?
Phosphate is the major food source for algae growth, once present this growth will be accelerated. Phosphate will also prevent other chemicals, such as sanitisers and algaecides, from working effectively. This means you will use more of these products which increases the cost of running your pool.
How Do I Prevent Phosphates From Getting Into My Pool?
There isn’t anything that can be done in relation to your incoming source water however additional phosphate can be reduced by the 3 “R’s”:
- Reducing runoff from gardens, landscaping or washing decks to enter the pool.
- Remove any leaves or rubbish from the pool regularly.
- Regular testing and treatment with Lo-Chlor Starver®.
Why Do I Need Starver® or Starver® X When I Can’t See Any Algae?
If you test your pool water for phosphate and it comes back positive this means the pool has the perfect conditions needed for algae to grow if left untreated. Removing the phosphate before any algae appear means that you are removing the food source and the algae cannot grow.
There Is Algae In My Pool But A Test Is Showing There Is No Phosphate?
If there is algae in your pool you can be sure there is also phosphate. If your pool water sample has tested negative for phosphate, even though there is algae present, this is because the algae have consumed the phosphate giving a false reading on the test.
Why Can’t I Just Use An Algaecide To Get Rid Of The Algae?
You CAN use an algaecide to treat the algae but the important thing to understand is that killing algae will only add more phosphate to the water. As the algae dies it releases its stored phosphate back into the water. This means new algae will grow even quicker than before and become harder to treat. Until the phosphate has been removed from the water the algae will continue to grow back.
Should I Use Starver® On A Regular Basis?
Yes, you should. Phosphate is continually being added to pool water from many sources therefore it makes sense to dose Starver® regularly as part of a weekly maintenance program.
