Test Kit Questions
I have a couple questions about the proper use of test kits. Number 1: When
comparing the resultant color of a sample to the color chart, the
instructions say to hold the sample up against a white background. Thatís
all well and good, but if I hold it directly against the white background I
get one reading, and if I hold it about an inch away from the white
background I get a slightly different reading. For example, this morning my
pH test read 6.4 if I hold it directly against the background, but only 6.6
if I hold it an inch away. This can make quite a difference when trying to
pinpoint CO2. Which way should I read the test?
Number 2: My SeaChem Phosphate test instructions say the test reads
inorganic soluble Phosphate. It says that if I want to test for
Phosphorous, I need to divide the test result by three. Which test result
is applicable to our planted aquariums, Phosphate or Phosphorous? It would
make a big difference because my tank would be extremely nutrient deficient
if Iím supposed to be dividing the test results by three.
Thanks in advance for any help!
