I started using my new Hanna PO4 meter but I'm not sure it works as it should.
I've read all threads here about the meter so I'm following what everyone says - take sample from the same place everytime (center of the tank), make sure there's no fingerprints, dust and the cuvet is very clean, agitate it until it is fully dissolved, do a instant reading and then a timed reading, etc.
In the begining I was getting inconsistent readings, 0.02, 0.25, 0.05, 0.17. Now I'm starting to get more consistent readings but it's 0.02 (like most people posted here).
I doubt the PO4 in my system is 0.02. The tank has a pretty high bioload and I haven't started using Zeo yet. And it's also strange that everyone else seems to get 0.02 readings as well.
Anyone else using this meter? Experiences?
