First time using a Hanna Checker. I have the low range Phosphate unit and got a reading of .93. My tank is just 6 weeks old.
Question is the conversion Apex Fusion does. When I enter. 93 and enter the correct HI713 test kit, the "result" number below says .32ppm.
When I go to the Measurements tab it shows the .93 reading.
Which one is correct and if someone could explain the two numbers? Thanks!
