Got a lot of API test kits today, and when I did the KH test, I had to use 17 drops before the water turned yellow. According to the chart, thats way over 400ppm, it stops at 12 drops! The GH is normal at ~53ppm, nitrites are too high, >5pmm, and nitrates are at 5, starving my plants unfortunately. Its a 14 gallon, going threw a mini-cycle with a half blind betta and some cherry shrimp ((I put them in after I thought the maincycle was done, so wrong was I)). I'm sure that if the KH is this high it can't be good, or can the test kit be wrong?
