Test results

Hanna, Red Sea & Salifert tests Red Sea and salifert close to one another Hanna is way different where do I go here ?

Tried multiple tests with consistency?
If it's off by 1-1.5 dkh from different test kits I wouldn't worry about.

I would just focus on keeping it stable with whatever test kit is easiest to use or read.

Hanna 8.2, Salifert 8.3 and near as I can tell you used the wrong dropper for the Red Sea alkalinity test (you use the small plastic dropper and count the number of drops - not how much you used or how much you have left). If there are markings on the tube you're using - that's not the right one.
(Addendum: I have the Red Sea Marine Test Kit, and I'm looking right at the alkalinity test - just in case anyone was curious).

I use the Red Sea pro with the titration and there is only 1 syringe that fits in the titration device
