Okay am I doing this test correctly, this is a red sea calcium test heres what it says to do. I will skip to step 8 and 9
8. open test tube, add one drop of calcium reagent A, close the test tube and shake gently,compare the color of the sample in the test tube to the end color on the color scale. ( I did this and it stays pink)
9. Repeat direction 8 adding one drop at a time until the end color is achieved, counting the number of drops added. (this is orange)
Now here is my question am I supposed to add that single one drop from step number 8 with step 9s drops? if I added step 8s one drop with step 9s 3 drops I woud get 4 drops, I then would come up with 4 +4 =8 x50 which I would get 400
ppm
if I didnt add step 8's one drop with step 9s additional drops then I would have 3 drops and add that with step #3's 4 drops I would be getting 4 +3 =7 then I would be X 50 to come up with 350
ppm
So am I supposed to include step 8's one drop with step 9s drops or what? sorry if this confuses you I appologize just want to make sure I am testing correctly..............Shaun
