The hanna PO4 gives unreliable results in RODI or freshwater.
The nitrate will work I think, but give a higher reading in fresh than salt.
In both cases they work pretty reliably in 50% salinity, so you can take the freshwater to be tested and mix 50/50 with some saltwater you know the parameters of, and figure it out that way.
