Anyone using the Merc Phosphate Kit
 

I have just done test on both my tanks and really can't believe I have readings of 0.0
I believe I have done what the instructions ask
fill both Vials to line
add 10 drops of agent 1
add 1 level spoon of reagent 2
shake until reagent is dissolve
wait one minute
compare 2 vials on chart.

Any one???
