Maybe you need a new one? I used to use API for daily checks on my breeding systems because it was economical. I wrote the date I opened them on the package and found they would wander in accuracy after about 8-12 months, but this is the case for most test kits and brands Ime.
Same results from one straight from the store. I don't believe these kits work at all.
The 5 in 1 test strips give real-ish numbers, but the dropper tests seem not to work at all.
