Thanks for the nice words.
If I didn't think it was great, I wouldn't be saying anything about it, I certainly wouldn't be defending it. I have been given lots of products that suck, and I don't defend them. This product is everything I have ever wanted in an alk testing device and more and I don't have one for the coral lab, but will be likely buying one in the new fiscal year.
But, I am not sure what that has to do with what I am talking to you about. The device needs a minimum number of tests a day to work properly over time. You seem to understand the concept, so I am confused what you are actually on about. Help me understand.
