Using Copper test kits with Cupramine

[Neptune 555]

I am dosing Cupramine in my 10G QT tank for 2 days now. I followed both the instructions on the back of the bottle and from this site thanks tylersarah

Cupramine dosing calculator:

(.381) * (strength of dose) * (gallons being treated) = mL of Cupramine to dose

Example: (.381) * (.5mg/L) * (10.5 gallons) = 2mL of Cupramine to dose slowly over a period of time

*On the bottle it indicates that 16 drops = 1ml.

I have added 2ml to my QT and tested using the API Copper test kit and my results are zero? So to test if the tester was the problem I added a drop of cupramine directly to test kit and it went seriously up... so what is broke here?

I added +8 drop to see if that would have an impact - test kit still reads zero?

Tank is 10G bare bottom with PVC HOB filter with only filter pad. I was running carbon prior but pulled it out before I started dosing. I am keeping the lights off to reduce stress?

Should I add more? Should I hold?? What is the gap? Cupramine does not show up with this test kit b/c???

If memory serves, I believe that you'd be better served by using either SeaChem or Salifert test kits when using Cupramine. The API kit will work on a chelated type copper, i.e. Coppersafe.

I have found the Salifert test to be easier to read, personally.

Correct. Many test kits, like API, don't work with Cupramine. Here's some vital info, the FAQ are really important. http://www.seachem.com/Products/product_pages/Cupramine.html
