Although phosphate is an important plant nutrient, too much can lead to algae growth. Phosphate is often present in tap water and is often introduced to aquariums as a result of feeding. Tetra Phosphate Minus (100ml) reduces high phosphate levels in aquariums via microorganisms that remove phosphate from the water. The gentle treatment is safe for use with all aquarium inhabitants, doesn't cloud the water during treatment, and is suitable for use in all freshwater aquariums.
Add 10ml of the solution per 40 litres of aquarium water. Each application removes up to 2mg of phosphate per litre (depending on the initial level). Repeat every two days until you reach the desired phosphate level. Make sure to supply adequate oxygenation during the treatment period.
