Anyone familiar with ELOS phosphate test kit?

I picked one up the other day and tested my water. First test was tank water, came up with .05. Second and third test was Topoff and tapwater respectively. Both tests just turned a milky white color, no blue color. Since I find it hard to believe that there is no PO4 in my tapwater, is it possible one of the reagents is bad? Reagent B seems very thick, and it takes a lot of pressure to squeeze one drop out of the vial. Is that normal?

sounds like a bad reagent it should not be that hard to squeeze out of the bottle.
