i really don’t understand how my phosphates could jump that much in the course over two days unless it’s a miss reading, none of my livestock is dead, no algae in sight im just worried i payed a pretty penny for a solid tester and now im probably gonna have to double back to my lfs to make sure. I test pretty often and im just not sure if this device needs to be calibrated? last time it was 7/13/2023. that was from
the factory and i’ve had it only for a couple months. if anyone else has this hanna tester please let me know.
