I wouldn't trust the test result either. We recently had a water testing session at my local club meeting, and the vast majority of tanks returned "0" using salifert's PO4 kit, including mine. One member brought an Elos kit that measured .07 on my water. Still not sure if that's 100% accurate, as I have good coloration and no hair algae problems. I'm debating picking up a Merck kit sometime down the line or a colorimeter.
While 0 is an admirable goal, commonly accepted practice is that .03 is a good target, as nsw tends to be .03 or lower.
