Hi all, I'm currently using the API master kit. It works well enough for most things, but I have a small problem... My betta is old, because of this I've been doing largeish (50-70%) pwc daily on his tank to keep his nitrates below 5ppm... That's my problem, the API kit doesn't register anything between 0-5ppm (and if it does, my eyes can't tell the difference in the colour) so I don't know what his nitrate is, all I know is its under 5ppm.. Is there a nitrate kit out there that will measure 1ppm, 0.50ppm ect? I test my tanks before and after each water change and write the results in my 'fish book', but its a little hard writing down results that I can't see..
Can anyone suggest a test kit (or the like) that will measure below 5ppm?
Thanks in advance.
Post Script: I know I don't "have to" worry too much if his nitrates are under 5ppm consistently, but my OCD likes to know what's going on in my tanks.
