Easiest to use and most accurate NO3 and PO4 tests
I am currently using some API tests for NO3 and PO4 this is what my LFS stocks. I have a hard time determining the difference between the colors on the PO4, and the NO3 shows zero but I would like something a little more accurate than 0,5,10 ppm etc...
So what are the best test kits for NO3 and PO4? Thanks! |

Hanna Checker Colorimeters are hands down easiest for phosphate..They don't make a nitrate..
For nitrate anything but API is "better"...  I've found the Nyos nitrate to be easy for the low range..

I use and like the Hanna ULR for PO4. JBL for NO3 and my younger daughter for color matching.

Salifert is good for po4 no3. Any sign of blue with the po4 test and you have po4 at 0.03 ppm or above. The no3 test goes down to 0.2.
