I am a bit colorblind so I have a hard time with the color changing test kits. I have the Hanna Phosphate and its reading 0, but I am fighting some green and red algae and the Nitrate test kit I have is hard for me to read.

Any suggestion on a kit I should look at?

Thanks

redsea for low range is great, but i dont know if you can see pink/purple or not

The only full solution for saltwater of which I'm aware is the PinPoint nitrate meter, but it is very pricey.

The reading is +/- 1 ppm when it is calibrated. Also, check out reviews. Some customers complain about the lack of consistency and meter drift after calibration. Not sure a reef aquarist would be satisfied with such a wide range.

Nyos kit is yellow/orange if that's easier for you than pink/purple.

I might have been a bit optimistic in saying "full solution", but the meter does work. The accuracy is limited, but it should be reliable enough if calibrated before every reading. That's about what I'd expect for a hobbyist ISE meter at this point.
