Should I calibrate my Apex to my Manual Testing or is the solution good enough? I ask because I noticed my Hanna Alkalinity checker is considerably higher than Apex reading
Hanna read 8.6 with the calibration of Trident solution. The solution is supposed to read 8.3 but it’s been open 48 hrs…I rechecked my tank water and it’s still reading 9.7.Trident should come with calibration solution to make sure working as designed. Use to keep ur trident working properly. When done use the solution with your Hanna. My Hanna checker was . 4 off from the solution.
Man thing is just stick to one reader for consistency
