  • Suitable for batch fertilisation
  • Combinable with MasterLine single nutrient fertilisers or complete fertilisers

1 ml MasterLine Phosphate per 30 litres of aquarium water adds the following nutrients:

MasterLine Phosphate is dosed as required if the phosphate concentration is lower than 0.5 mg/L.
The recommended dosage is only a guideline. Depending on the aquarium, the dosage of the fertiliser can be reduced or increased to achieve optimum results.
