Ratio N:P and NO3:PO4
N:P 16:1 marine
N:P 10:1 aquatic
N:P 10:1 = NO3:PO4 10:0.69 = NO3:PO4 14.5:1
-------------------------------------------------------
Ca testing
((17.86 x dGH) (4.1 x Mg ppm)) / 2.5 = Ca ppm

(ppm dGH - (4.1 x Mg ppm)) /2.5 = Ca ppm
-------------------------------------------------------
Mg testing
((17.86 x dGH) - (2.5 x Ca ppm)) / 4.1 = Mg ppm

(ppm dGH - (2.5 x Ca ppm)) /4.1 = Mg ppm

Hagen Nutrafin, Ca test in 10 ml
((20 x GH drops) - (25 x Ca drops)) /4.1 = Mg ppm

Hagen Nutrafin, Ca test in 5 ml
((20 x GH drops) - (50 x Ca drops)) /4.1 = Mg ppm
-------------------------------------------------------
GH testing
(2.5 x Ca ppm) + (4.1 x Mg ppm) = GH ppm

((2.5 x Ca ppm) + (4.1 x Mg ppm)) / 17.86 = dGH
-------------------------------------------------------
Test Kit calibration
To get to know the product line, make a test solution and see how the colors look like. This way you know what you are dealing with. Different lighting, wall paint, etc. change results dramatically. You can use a regular kitchen bucket ~2.5 gall / 10 liter and PPS solutions.


NO3
KNO3 - 20 gram in 500 ml (or SS - Standard Solution by PPS-Classic)

2 ml in 10 litre = 5 ppm
4 ml in 10 litre = 10 ppm
8 ml in 10 litre = 20 ppm
12 ml in 10 litre =30 ppm
16 ml in 10 litre = 40 ppm
20 ml in 10 litre = 50 ppm


PO4
KH2PO4 - 6 gram in 500 ml (or SS - Standard Solution by PPS-Classic)

2.5 drops in 10 litre = 0.1 ppm
5 drops in 10 litre = 0.2 ppm
12.5 drops in 10 litre = 0.50 ppm
25 drops in 10 litre = 1.00 ppm
50 drops or 2 ml and 10 drops in 10 litre = 2 ppm


NO3
KNO3 33 gram in 500 ml (or #1 Solution by PPS-Pro)

25 drops in 10 litre = 5 ppm
2 ml and 10 drops or 50 drops in 10 litre = 10 ppm
5 ml in 10 litre = 20 ppm
7 ml and 10 drops in 10 litre = 30 ppm
10 ml in 10 litre = 40 ppm
12 ml and 10 drops in 10 litre = 50 ppm


PO4
KH2PO4 6 gram in 1 litre (or #1 Solution by PPS-Pro)

5 drops in 10 litre = 0.1 ppm
10 drops in 10 litre = 0.2 ppm
25 drops in 10 litre = 0.5 ppm
50 drops or 2 ml and 10 drops in 10 litre = 1 ppm
5 ml in 10 litre = 2 ppm

Deficiency symptoms on Mobility and Immobility of nutrients:
Ca, Fe, Mn, Cu, Bo, S, Zn, Ni, immobile, symptoms on young parts of plants
N, P, K, Mg, Mo, Cl, mobile, symptoms on lower or older parts.
-------------------------------------------------------

1 dGH
7.144 Ca ppm = 1 dGH = 17.86 ppm GH
4.356 Mg ppm = 1 dGH = 17.86 ppm GH

Ca : Mg [ppm]

7.0 : 0.0
6.0 : 0.7
5.0 : 1.3
4.0 : 1.9
3.0 : 2.5
2.0 : 3.1
1.0 : 3.7
0.0 : 4.4
-------------------------------------------------------
TDS uS ppm Conversion
There are two ways to measure TDS. The [s] Siemens and [ppm] as NaCl equivalent. Both test equipments are identical except the calibration part. The two can be converted as follows
uS = 2 x ppm
ppm = uS / 2
