I AGREE 100% with the difficulty in reading the low range. I just ordered a Salifert Nitrate, nitrite, and Mag tests. I already use Salifert for ammonia and Calcium. I use Fastest for PH. I would like to know more about Fastest for other tests though as they aren't as complicated as Salifert. Although I think complicated is not the right word...maybe complex. I don't know. I do like that with Fastest you just dump the foil package in your water vial and shake it up. DONE.
Anyone have any input on Fastest for ammonia, trites, and trates????
