seawolf said:i'm new to plants and dosing, and i'm trying to figure out what i need to buy and how to mix it.
This post explained alot but i started getting lost after the first page
so far i have come to the idea that i need to buy the following powders.
kno3- potassium nitrate
kh2po4- potassium phosphate
mgs04- magnesium sulphate
and trace elements mix.
i plan to mix this with water in these quatities for a 100 litre (25us gal) tank with just over 3wpg lighting
in 600 ml of water to provide 12x 50ml doses
i will dose the trace elements on different days
now for the question.....Aqua essentials sell alot more powders than the ones listed above, so do i have the right ones, and do i need to add/ remove anything from my planned mixture?
Always separate the CSM+B from the NPK because it has a tendency to react with the phosphate. You can dose the CSM+B as a powder or if it more convenient add 8 * 1/16 tsp => Â½ teaspoon to 200 ml of water and dose 25 ml two times per week.

No difference whatsoever mate. In fact I think Epsom Salts is actually the heptahydrated form MgSO4Â·7H2O.
