Best Nitrate Test Kit

[Wlachnit]

What are people's favorite nitrate test kit and why?

I have been using mostly Salifert lately, but the color change is so subtle that it is hard to tell if you have 5 or 25 ppm nitrate. Before that I was using Seachem but noticed that it read consistently much lower. I did some research on that and that is to be expected because the Salifert test doesn't suffer from amine interference.

Anyway....what are people's experience?

I use Red Sea pro. It's only good for lower levels (like <5) but can def tell the difference between small gradations on the low side of things. There is a dilution to measure higher levels, but I think it's harder to read and I'm less confident with the results.

I use Red Sea. It's the only Red Sea test I use, but it's the easiest Nitrate kit for me to read.

Hoping Hanna comes out with a marine version.

I talked to Hanna at a scientific conference a few months ago and the challenge for saltwater is the interference from chloride. What I don't understand is why they just don't take the existing manual tests and automate it with a handheld checker, rather than trying to adopt the freshwater checker....
