Removes phosphate, a key contributing factor for algae growth



If algae is present, it is recommended you treat this algae first with one of the Lo-Chlor Algaecides prior to beginning phosphate removal.

  1. Backwash the filter, check filter pressure and adjust pH to 7.2-7.4.
  2. Use a reliable phosphate test kit to establish the phosphate level in your pool water.
  3. Shake the container for a minimum of 30 seconds and add the required dose (see dose rate below) slowly into the skimmer with the pump and filter running.
  4. Check filter pressure after 48-72 hours. Backwash the filter and add a maintenance dose.

Please Note: Starver® is suitable for use with Sand, DE & Glass Filter Media and not for cartridge filters.


Initial Dose

For a phosphate reading up to 1ppm (1000ppb) add Starver® at a rate of 500mls per 50,000 litres of water every 2 – 3 days. For a reading greater than 1ppm (1000ppb) but below 2ppm (2000ppb) add Starver® at a rate of 1 litre per 50,000 litres of water every 2 – 3 days.

Maintenance Dose

For a phosphate reading between 0–0.2ppm (0-200ppb) a regular maintenance dose of 500mls per 50,000 litres water is required every 2 weeks.
The required dosage should be added until you finish the container.
