I could deal with it if my photometer read .01 and theirs said .04, but 1.24? No way. I felt compelled to return a small essay, but now it's time to vote with my feet, as they say. The Lab Aquatics site looks pretty good based on the sample report they provide. At least it shows a phosphate level of .03 or so, which would be a -1.21 at the other place :-)
