I wonder if the variation in phosphate is the variant of the Hanna Checker. 

What is the variant?

+/- .04, So I technically could be at .08 Po4 and still get my readings at .12 and .04 which have been my last few readings. 

You must be using the HI713, the HI736 is +/- .015

Yeah I am not using the ultra low range. I have it, I just haven't opened the box yet. Figured I would use all my reagents first and then try out the ULR.

You’ll like it!

Yeah, it is not something that I constantly pay attention to, but it is something to keep in the back of your mind. Especially, when you are monitoring closely. Every test kit(Hanna, Salifert, RedSea, API) has a variance to take into consideration. Each test kits margin of error is different, so it is important to consider when comparing test results from one kit to another. In this instance, that could totally be the reason for my difference in my results every few days.
