How to evaluate the test strip results?
I live in a Chicago suburb, so I've heard it's probably that I have hard water (my dad guessed we have soft though, since we never get mineral lines in the toilet etc). I bought the API gh/kh/ph test strips, I couldnt find anything more reliable than the strips at the LFS. I tested the tap, and also my tank water (its a heavily planted NPT running for over a month now). Both tests resulted similar. My pH was somewhere between 7-7.5 (im bad with those colors), but I would lean towards 7.5 for sure. My gH was between the last two highest colors (120ppm-180ppm). I would say it looked like a dark 120ppm, but then again i saw shades of purple which indicates the 180. My bet is somewhere inbetween.
When i look at fish profiles in this site, you use low numbers measured by dGH for hardness. How does ppm translate to dGH?
Do my readings look normal? Especially if anyone is familiar with Chicago water. I would ask what types of fish are good for my water in a heavily planted 10g, but ill save that for another thread. Thank you for your help.
