How accurate are these? My API has been all over the map with testing. One day it seems like 15, the next 5, then 10. I have a hard time with yellow/orange. I got a Salifert test and it was so much easier to read and was very clearly at 2.5. Using the regular method and the low method both were at 2.5.
Anyone have issues with that test? I do have a fair amount of GHA so I was kind of expecting it to be higher than that (phosphates test at 0).
What about Salifert ammonia test? The API has been showing about .1 all the time. The Salifert was even harder to tell with. It was no more than .1 and may have been 0. It didn’t really match anything on the card. I think I’m color challenged lol
