Hanna Checkers for Ca/Alk/Mg/NO3

I have the Phos, alk and calc checkers. I love them, but I'm extremely biased as I'm partially color blind. Comparing colors.. HA.

 

I just saw this and realized that I should go back and finish my review. Because my opinion has drastically changed. The Cal. checker has a few issues with it. And there has been quite a negative response from most hobbyist. The problem using 98 percent RO/DI for this test is that you can have cal. in your RO/DI. And that the syringe that is included with the kit to add the 1ml of saltwater is not efficient at all. Hanna themselves have admitted to this, and have suggested going to a pharmacy and buying diabetic syringes for a more accurate reading.

I am sure that hanna will respond to this, and update their test kit. So maybe when they do, I will go back to it. But after all the issues that I had with it, I was happy to return to my API and Salifert test.

 

thanks think i will wait on this checker, i want to make it easier not harder to test.
