Hi,
I am running an ultra low nutrient system (PO4 at .04 - .09 and NO3 at around 2 - 3). I have the Phosphate UL digital hanna test kit - which works great, easy and quick. My challenge is testing for NO3 and currently using Nyos NO3 test kit and difficult to get accurate reading due to matching colors - especially at a low range from 1 - 5 ppm. I do know that Hanna does have the Nitrate low range digital kit HI781 - but many complaints on the pain it is to use as I am hearing.
I am looking at purchasing this one from Hanna - more expensive and trying to not spend money on useless equipment so want to make sure there are some folks using this with success.
Thanks
