Hello, I would like to purchase a PH Testing Tool (not a test kit) to monitor PH. I do NOT have an Apex. I know there are two basic options...(1)...instant read handheld such as the Hanna Pocket Tester Option or the HM Digital PH Pocket Tester...and there are probes that monitor 7/24 offered by Hanna and Milwaukee. I was wondering what others are using and Pro's / Con's ....I am leaning towards the Pocket Tester as I do have 3 tanks and would be nice to use it for all 3 tanks..just not sure of the accuracy compared to the probe models.
Any feedback is appreciated..thanks in advance
