Hello guys so I just bought a Hanna alk checker and even despite using Red Sea black bucket of salt mixed at 35 (checked with two calibrated instruments)
I keep getting a Hanna checker reading 7.2-7.8
Why is my Hanna this inaccurate
I even tried a precision 10 mm syringe I have, and it’s still will not fix it
