Hanna Phosphorus ULR Reading

[Geebs19]

I just got the Hanna Phosphorus ULR and did a check of my rocks that are currently curing in salt water. I got the reading at 27, is that mean its .027 ppm?

You can search for the calculation, I just use the apex and it converts it for me

Glad I asked, I knew it wasnt that easy of a conversion haha.

(Reading x 3)/1000

This will get you really close to your phosphate in ppm.

3.066 x reading divided by 1000 or just multiply by .0031. Remember there is a margin of error.
