I've had trouble getting readings with the Hanna PO4 tester. I always get a reading of 0 even though I have a bunch of hair algae and turf algae growth as of late. I'm thinking the po4 is being consumed faster than it can be detected by the meter and thus I feel PO4 testing is overrated. I am curious to see what kind if readings you get with your meter.
