hi,

100 liters = 25.5 us galls, after substrate/hardscape displacement, you can dose for a 20 us gal tank!
dose this, eg monday, wednesday and friday.....
NPK (Nitrogen+Phosphorus+Potassium) Mixture for 20 Gallon Tank
1 month = 4 Weeks
3 doses of NPK per week
Therefore there are 12 doses of NPK per month.
Multiply a single dose teaspoon value by 12 => [3/16 tsp KNO3]*12 = 2 ¼ tsp KNO3
[1/16 tsp KH2PO4]*12 = ¾ tsp KH2PO4
[1/2 tsp MgSO4]*12 = 6 tsp MgSO4
Add these to 600ml of tap or distilled water
also dose this, eg tuesday and thursday...
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 => ½ teaspoon to 200 ml of water and dose 25 ml two times per week.
just swap csm+b for the trace you have bought!
hope that helps,
and thanks to clive,
cheers!
