PlantGuy's Magnesium Sulphate- MgSO4

Feeding plants

To make a typical stock solution for feeding plants add 70g (4.6 tbsp) of dry MgSO4 to 500ml (16.9 fl. oz.) of RO or distilled water and then add once a week 50ml (3.3 Tbsp.) of this solution per 100 Litres (26.4US G.) of tank.

This will give you 7ppm (7 mg/l) of Magnesium.

• See EI and PMDD.

• Also used in a ration of 1:3 with CaSO4 (Calcium sulphate) (1 part MgSO4:3 parts CaSO4) to make your own GH mix for a freshwater aquarium.
