Algae Starver Fresh Water Aquarium Phosphate Remover 4 litre

Liquid phosphate remover - dramatically reduces phosphates. Algae Starver is a liquid phosphate remover, reducing the phosphates to such a low level that it starves the algae, causing it to perish. Controls the algae, leaving you with an algae free aquarium. Safe for fish, shrimp, snails, turtles and other aquatic life. 1 litre treats up to 20,000 litres of water. 

Directions: Add 5ml to 100 litres of water every 2 to 3 days. If phosphate levels are greater than 1ppm, Algae Starver should be used at 5ml to 50 litres until algae subsides. Once you have completed the treatment, take a water sample to your aquarium or pond professional to be tested for phosphates. Once you have achieved a phosphate level of less than 0.02ppm you should add a maintenance dose of 5ml to 100 litres every 2 weeks. More effective in alkaline water.
