Potassium sulphate (K2SO4)

Under ideal conditions, an aquarium uses a maximum of 30 ppm potassium per week. Adjust the dose to suit your plants, lighting and CO2 level.

Instructions for use:
Dissolve 45 grams of K2SO4 in 500 ml of warm (preferably reverse osmosis) water. A dose of 10 ml per 100 litres raises potassium by 4 ppm.

EC fertiliser. Simple fertiliser. Potassium oxide (K2O) 51%, Potassium (K) 42%.
