Hi guys, what are the numbers do you see on this reading? I'm seeing a number between 0 - 0.25ppm. What do you guys see? My nitrites is at 0ppm and nitrates between 10-20ppm. Iam not quite sure if misterhamster(Jardini) is doing alright, he seems to be staying in one corner of the tank when I'm around. But I do catch him swimming if he doesn't see me. Just got him 2 days ago by the way.
