I am using a Hanna phosphate checker to keep track of my phosphate levels. I am wondering what test number to use. I can test twice and get two different results. Test a third and it may match the second or slightly off.
Last night...test 1---.08_____test 2---.03
Tonight...test 1---.05______test 2---.01
Which is accurate? I don't really want to blow through the reagent using two per testing period.
