Liquid phosphate binder—dramatically reduces phosphates. Excessive amounts of phosphates can lead to serious problems in your aquarium, including green water, unpleasant odour or too little dissolved oxygen. Starver-f corrects phosphate levels and is 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, Starver-f 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.  Acidity can reduce effectiveness.
