Regarding the Salifert Marine Alk
tests (which I really like), I have a question about adding the reagent (the last step in the process)
The instructions indicate to add 1 drop of reagent, then shake the test solution a little, then 1 more drop, then shake a little, and so on.
To save time, i.e. if you know approximately how much reagent you'll need to get you close
to the point where you're adding those "last drops" with a shake inbetween to achieve the final color change
, my question is this:
Does it skew the test results at all to shoot those first
20-30 drops in without shaking between each one?
Or, is the test user instructed to do this simply so as to not "go past" the point of color change, (overshooting)
I was going to sit down and do about 5-10 controlled tests right after the other from one tank, just to see if I got different results with shaking or not shaking with the first 50-70% of added reagent. However I wanted to check with y'all first.
