Hey guys,
I recently bought an Hanna Nitrate Colorimeter Tester and it gives me a double dose result.
I did a reference solution of KNO3 using Rotalabutterfly fertilizer dosing page.
This is the result :
So i dosed 10ml of that solution in a 2L container. When i do the test it should gave me around 10ppm but it reads 20ppm. I am wondering is the math on rotalabutterfly off or my KNO3 isn't really kno3 or i have a defective unit ?
I did this reference test because last week when i did front load my aquarium it gave me a double dose result as well.
i test that out with spoon measurement and via scale (incase i had a defective scale) both gave pretty much the same result.
