What’s my po4 at?

[cginter]

I’m using the Hanna ULR and getting a reading of 33-35 after two test. I was told to multiply my reading by 3.066 then divided by 1000. Which would give me a reading of .101-.107 is this correct? Seems high to me.

33 would be .1 ppm.

Confirm is high. Try to keep PO4 in the range of 0.02 to 0.08
