PPB, PPM (PO4)

[fishyfishyfishy]

Hi fellow reefers,

I recently got a hanna ultra lower checker which measures at parts per billion(ppb), and i got a reading of 8 !

May i know what is the correct method to convert to ppm and there was some debate over it's reading as PO4 and reading as phosphorus.

what i gathered so far was that i need to convert to PO4 by multiplying by 3.066 as my reading is in phosphorus and divide by 1000.

Is this info correct ?

Yes theoretically, You can convert phosphorus (P) to phosphate (PO4) by understand Molecular weight ratio. This is what Hanna instrument using...

phosphorus * (95/31) = phosphate (ppb)/1000 = phosphate (ppm)

Cheers & Happy Reefing..
