Accurately reading the color scales is tough enough with the supplied printed versions. Having a scan done (with unknown settings) and then sent to you and printed out on a printer, also with unknown settings, is really going to put your tests in the guessing game department. Eventually you will be needing more test liquids anyway, just buy another kit and save yourself the possible problem of being way out on your tests.
Just call or email Hagen and they will send you one out right away. Just tell them what you need and give them your mailing address. I got two of my Hagen manuals wet and this made the pages stick together. I emailed them and I had my new manuals in a few days.
I recognize that a scanned version is not as good as a real booklet, but since they're not precise to start with, the generalities may be suffice to see HOW BAD my nitrates really are.
To buy another one would be a waste, since this is an otherwise fairly new bottle and to wait a year+ to finish it and start the one I bought extra simply for the book would, possibly, deminish accuracy again since the product would be old.
I will call Hagan, I was simply trying to get a rough/immediate estimate of the problem with my tank.
There was no charge from Hagen when they sent me the directions.
Here's a little help but you'll have to use you imagination some. The Hagen chart only has 5 different colors and 5 different ppm concentrations. The medium pink colors are very close together on the direction's color chart. The dark pink colors are very close as well. In other words, there's not much difference in the color from 10 to 20 ppm (medium pink). Also there's not very difference in the color from 50 to 110 ppm (dark pink). 5 ppm (pastel pink) is easy to determine. So, there's basically only 3 different ranges.
Pastel Pink: 5 ppm
Medium Pink: 10 to 20 ppm
Dark Pink: 50 to 110 ppm
The EI target range for nitrate is from 5 to 30 ppm. So, if your test solution is a pastel pink or a medium pink color, you're OK. If it's dark pink, well....
Here's the directions:
1) Take a sample of the water to be tested with the pipette. Use it to fill a clean test tube to the 5 mL line.
2) Add 5 drops of Reagent #1 and 5 drops of Reagent #2 to the test tube. Insert cap. Hold in place with finger and shake well to mix. Always use the cap. Avoid skin contact.
3) Shake the Reagent #3 bottle vigorously (5 sec.) and add 3 drops to the test tube. Insert cap. Hold in place with finger and shake well to mix.
4) Wait 5 minutes for the color to develope, shake again, and match the test color to the closest color on the chart.
Maybe this will get you a little idea about the NO3 concentration in your tank. I tried anyway.
