Cool. This is far more effectiveness than I would have predicted.

I don't use the LaMotte kit, but I did use the AP kit and I found it
unreliable. It always read high and even registered significant PO4 in my
tap water, which is pretty much phosphorus free according to lab analyses.
I attributed the problem to a false positive caused by silica in the
water, but there may be other problems as well.
