Only if you where to add more water than had originally evaporated.
The blue color on the test kit is very difficult to read. I used the refrence test and it did show a blue color. Should i add more cupramine to the water i don't want to od the fish.
Be sure you know what the current level of Cupramine in the system is or you will not know what amount to add to get the correct dosage in the QT
If the sample regent supplied with the kit registers correctly the test should really be okay. Try repeating both tests (with sample regent and QT
water) to see if you had an error in your steps somewhere while testing. For a 10 gal QT
the dosage should have been 1 ml the first day and another ml in 48 hrs. If I remember correctly that's the equivalent of 20 drops each dose.
