Hi All,
1st let me introduce myself, I'm principally a Discus keeper (link to here from BIDKA).
I live in south Lincs and have a 300 gallon planted tank (21 discus) and a 60 gallon planted tank (2 Discus), both use UG filtration+cannisters and UV.
I have been reading the artical (great stuff ) re EI and was doing OK, untill I came across this;
"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
Now this mixture must serve 12 doses so each dose is 600ml/12 = 50ml
This makes life easier because you need only dose 50ml of this NPK solution 3 times per week.
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 300 ml of water and dose 25 ml two times per week."
NPK I'm ok with, adding dry salts, no issue, but would somebody please enlighten this 'newbie' as to what CSM+B is??
Many thanks in advance, Cheers, Mick B
