Algae Knock-Out (Lochlor)

Controls blue/green and black and mustard algae in swimming pools.

Originally developed for ALL types of algae, Lo-Chlor Algae Knock Out is now widely known as the No.1 treatment for stubborn algae strains in pebble pools and ageing pool surfaces. Available in 2.5L and 5L packs.


  • Use in all types of pools.
  • Effective against blue-green, black spot and mustard algae.
  • A favourite for pebble surfaces and ageing pool surfaces.
  • Especially popular with salt chlorinated pool and ionised pools.
  • Quaternary ammonium base – dual action formulation.

As well as lysing the algae cells, the increased detergent action (foaming) assists in releasing the clinging algae crusts from pool surface. For severe algae infestations use in conjunction with Lo-Chlor Black Spot 900 Algaecide. Remember – always test for phosphates after the addition of a Lo-Chlor Algaecide.

Dosage: 2.5L treats 50,000 litres pool water
