Maybe 1 gram or 1 teaspoon for every 3.8 litres of water.
So for X litres of water, the amount of epsom salt to add would be approximately :
X/3.8 gram for 'X' litres of water.
So if using X = 1 litre of water, then put in (1/3.8) or 0.26 gram (ie. roughly a quarter of a teaspoon) into 1 litre of water.
1 gram won't be exactly the same as 1 teaspoon of epsom salt. This is just an approximation.
