Hanna Checker P04 Levels

[christopher.lauwers]

Hello,

I am not sure which I should be using to record p04 levels, currently ULR p04 reading using a Hanna checker is 9.

The Hanna chart I found on line says 9 PPB = 0.028
When I use fusion it records 9 at 0.03
I get that it might just be rounding... but my concern becomes when I get into single digits

Using a ULR reader what should my target be for p04?( mostly SPS small - med frags at the moment) and should I use the Hanna chart or Neptune?

or am I just wayyy over thinking this

Neptune rounds to two digits the result in fusion, it won't make or break your tank to be at 0.020 vs 0.030. As well, keep in mind the tester itself has a margin of error even under ideal conditions. I would be happy with that level of PO4

Thanks for the reply... just handy to have it recorded in fusion. Seems when I try and write it down on paper someone(kids) get into my fish gear and like to color my charts
