Question About Potassium

[danski]

if im already dosing potassium nitrate, and mono potassium phosphate..would i still need to dose potassium seperate or would these two be enough..im confused as to wether or not i still need to dose potassium..would csm+b cover the potassium i need..or would i need more than csm+b can provided?

If you are dosing EI then there should be sufficient K in KNO3 alone. Some dose extra K2SO4 to rule out any K def. possibility, "overdosing" K has no ill effect on fish or algae.

If you want add K2SO4 then add 1/16th teaspoon 3 x week per 100 litres.
