AAA Magnesium Sulfate MgSO4

Magnesium Sulfate (MgSO4) is a source of Magnesium (Mg), a component of chlorophyll and the transport of Iron (Fe).  Sulfur (S) is essential for root development.


Magnesium Sulfate Heptahydrate(MgSO4)   

Magnesium (Mg) ……………………….  16.0%

Sulfur(S) ………………………………..  32.0%

To make a typical stock solution add 105g of dry MgSO4 to 500ml of RO or distilled water and then add 24ml of this per 100L of tank.

this will give you 5 ppm increase of MAGNESIUM

The target is 5 ppm per week if you useEI METHOD 

Dosing:  1g of MgSO4 with give you 1 ppm increase of MAGNESIUM in 100L (26 US gallons) of water.

The target is 5 ppm per week if you use

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.

Amounts above are for reference only.  Your planted aquarium may need more or less depending on many factors.
