You should read/study about a method and apply it. Go to BarrReport.com for the Estimative Index theory. Maybe you try PPS Pro instead.

Regardless of the method, you will need to understand much more than just "this many grams of K2SO4 into my tank".

Some keywords for you to research: Macronutrients, Micronutrients, concentration, Estimative Index, etc.

Hi all,

You can use the dosing calculator at <"Rotala Butterfly">, or you can work it out from the percentage of potassium in K2SO4.

You need to know the RAM of the elements, K = 39, S = 32, O = 16 and the RMM of the compound (2*39) + 32 + (4*16) = 174.

The potassium content is 78/174 ~ 45% K.

When you make up 1g of K2SO4 to 1 litre of water you have added 0.45g (450mg) of potassium, and mg/L is equivalent to ppm, so your solution is 450ppm K. If you add 1g K2SO4 to 10 litres of water you've added 45ppm and 1g to a 100 litres, 4.5ppm K.
