I just received the water quality test (TDS
tester) that I ordered online today. It measures in ppm
. So I checked the available water in our house now. Carbon-filtered drinking water is 29 ppm
. Tap water from kitchen sink is 78ppm. The QT water coming out the filter is 92 ppm
. And the worst, 20 gallon tank water that is coming out from the filter is 102 ppm
I don't know what kind of stuffs this thing measures. But surely, based on the ppm
measurement, the 20 gallon tank has more stuff than the carbon-filtered drinkable water. It could be bad or good. Heres a factor I have in mind: the high ppm
from my 20 gallon might be due to the high nitrate and nitrite (as the person from the aquatic store mentioned) and probably other stuff such as conditioners ingredients.
Does anyone have experienced using water quality tester? Based on the given accepted ppm
measurement, the 102 ppm
measurement on my 20 gallon tank is under the acceptable water.
Here's the given table:
0-50 ideal drinkable water, RO
, distillation etc.
50-100 carbon filters, mt. Springs, aquifers.
100-~200 hard water
~200-400 acceptable tap water
400-500 high TDS
from tap or mineral springs
500+ US EPA's max contaminated level
