Hi All! So after reading many different threads I decided to upgrade from the api kit to the red sea test kit. I dont have any coral in my tank, but do have some button zoas. My zoas arent looking too hot and I read they do best in higher alkalinity so decided to test. I admit this was my first time testing my KH. So here is my problem..as I understood the instructions, one drop of the titrant should have brought my 5ml sample to the "start" color. It barely changed my water color. I actually had to add five drops. Now Im not quite sure how to read my results. Any assistance would be much appreciated, but Im going to assume right off the bat that my KH level must be off. Question is....is it too high or too low??
