OK Ive read the EI article and would be grateful if someone can have a quick look to make sure I'm understanding the maths correctly.
My water is neutral pH and medium hardness.
I have these salts....
MgSO4 (magnesium sulphate),
K2CO3, (Potassium Carbonate),
KH2PO4, (Monopotassium phosphate),
KNO3, (Potassium nitrate).
TNC Trace
My tank, for estimative purposes is 40 UK gallons and my lighting is 78W of T5 so Im calling that 2wpg. (Is this low medium or high lighting btw) ?
The article says...
Sunday – 50% or more Water Change then dose [3/16 teaspoon KNO3] + [1/16 teaspoon KH2PO4] + [½ teaspoon MgSO4]
Monday – 1/16 teaspoon CSM+B
Tuesday - [3/16 teaspoon KNO3] + [1/16 teaspoon KH2PO4] + [½ teaspoon MgSO4]
Wednesday - 1/16 teaspoon CSM+B
Thursday - [3/16 teaspoon KNO3] + [1/16 teaspoon KH2PO4] + [½ teaspoon MgSO4]
Friday – Rest
Saturday - Rest
From the above values based on a 20gal tank Im doubling as mine is 40gal appr. Giving
Sun 3/8 tsp KNO3 + 3/16 tsp KH2PO4 + 1tsp MGSO4
Mon 1/8 tsp Trace
Tue 3/8 tsp KNO3 + 3/16 tsp KH2PO4 + 1tsp MGSO4
Wed 1/8 tsp Trace
Thy 3/8 tsp KNO3 + 3/16 tsp KH2PO4 + 1tsp MGSO4
Fr/Sa REST
weeky totals therefore
KNO3 = 1+1/8th tsp, KH2PO4 = 9/16th tsp, MGSO4 = 3 tsp, TRACE = 1/4 tsp
Multiply x 4 for a 1 mths supply to be mixed in 600ml water
KNO3 = 1+1/8th tsp x 4 = 4 1/2 tsp
KH2PO4 = 9/16th tsp x 4 = 3 1/4 tsp
MGSO4 = 3 tsp x 4 = 12 tsp
TRACE = 1/4 tsp x 4 = 1tsp
OK So
1) Are my calculations correct ?
2) Where does the K2CO3 come into things or do I not need it ?
3) Do I need to adjust this based on my lighting levels of 2wpg ?
4) Am I right that the CSM+B in the article is the same as TNC trace ?
Sorry for such a long post....
