looks like 20 on my screen.40 nitrate in my saltwater tank
Is this a bad level
Personally i would shoot for <25ppm, but i've had periods where my nitrates are just around 50ppm. the problem with color tests like this is that it can be kind of hard to get a perfectly accurate reading. I'm color blind, so I generally struggle (and always get a second opinion). I would continue to do your water changes, test, and I'd take a hard look at how much you're feeding, that's your most likely cause of higher nitrates (IMO)Is this a bad level
