Expectation really outdone!

I was previously skeptical about whether this "TESTLAB" all my water values ​​could be as comprehensive and accurate provide information on (almost) ...
(Based on the positive recessions here I have but then decided to buy!)
This is the latest version (batch CH / B 0003) by MS Noah's Ark with the following additional tests:
Silicate Test - SiO2, pH test - pH 7.4 to 9 and an oxygen test - O2
to the already described tests: pH 3.0 to 10 2x, pH 6.0 to 7.6, CO2 table, 2 x GH, 2 x KH, PO4 phosphate, ammonium NH4, 2 x nitrite NO2, NO3 nitrate, iron Fe
All test series are explained clearly and fairly easy to use. There are a number of small glass cuvettes.
Finally, I know that, for example, ruled in my pelvis chronic iron deficiency (despite occasional fertilization), but my "city water" is supplied from the waterworks very, very abundant silicate! Overall, the investment has really paid off already after one month because I could greatly improve the water quality!
