I am using the red sea kits for Alk,Cal, and Mag. I seem to have a little trouble determining when the color really changes. For instance with Alk - I tested several times and get somewhere between 7.0 and 7.5. That range seems to be a little to great. I realize it is a little subjective based on when the color actually changes.
I'm using the Sailfert Phosphate test, which is just about useless to me.
So my question is should I get a Hanna checker (for Alk and Phospate)? Are they really that much easier to use and more reliable. Is there any subjectivity to this test as well?
