Well let me see if i understand everything
I'm used to liquid solution, litters and grams so i will use this units
and i will use
Chuck's online calculator
I'm going to try EI in a 30 litter water tank (7.93 gallons) so will pick the 10-20 gallon example (off course i will reduce a little the fertilization, but thats a detail for now)
10- 20 Gallon Aquariums
+/- 1/8 tsp =
0.125 g of KN03 (N) 3x a week
+/- 1/32 tsp =
0.15 g KH2P04 (P) 3x a week
+/- 1/32 tsp (2ml) Trace Elements 3x a week
50% weekly water change
As i say i will make a 250 ml of KNO3 and 250 ml of KH2PO4 and i will fertilize 5ml 3x a week. So by my math:
KNO3
6.2 g for 250 ml = 0.51 ppm => 0.51 ppm * 5 = 2.55 ppm = 1/8 tsp of KNO3
KH2PO4
7.5 g for 250 ml = 0.7 ppm => 0.7 ppm * 5 = 3.5 ppm = 1/32 tsp of KH2PO4
Please let me know if this math is correct!
This is a simple example of what to do to convert dry ferts in solutions ferts
