You can use Chuck Gadd's Dosage Calculator to find out. I did a quick calculation... 100ml of that in your tank will give you 4.39ppm of K.

10g is hard to measure unless you have a scale. 2 flat standard teaspoon mixed in 1000ml, will give you 5.27ppm with every 100ml.

Might be easier if you mix 1 teaspoon into a reasonable amount of water and pour the whole solution in. That will give you 26ppm of K.

Thanks Vinz
I got it now.
I will try to add 1 teaspoon into 500ml of water, and use this soluation into tank, so 500ml will give me about 25 ppm of K, it should be ok right.

Weileong.

are u serious when u say u are looking for potassium nitrate? that's an ingredient for explosives n' is tightly controlled in the market.

hmmm... u are not a terrorist in the making right? :P

KNO3 is not controlled and is easily available. So is NH4NO3... another potential raw material for making explosive.
