I have this kit. It's pretty easy to use. I always use it under the same bright white fluorescent lamp so I have good, consistent lighting. It's quite easy to tell the difference between 300 and 400 ppm. I'm confident I can use the kit with +/- 15 ppm.
FWIW, my maintenance is about the same as all you guys. I test SG, Ca, alk, Mg, K once a month-ish, and it takes maybe 15 minutes because I have them all going at the same time. :lol: NO3 and PO4 maybe quarterly just for interests' sake. |
