What’s the most accurate?
Honestly, they can be more or leas accurate based on the age of the reagents, how well (or not) you clean the vials, how accurately (or not) you follow the testing procedures, etc.

I have Hanna to get precise measurements every few weeks or so, but I like certain test kits for ease of use, ie: Red Sea Marine for pH, ammonia and alkalinity, Nyos for nitrate and phosphate, Aquaforest for magnesium, etc.

This x1000.

With that said, some of us are color blind, and can't see the subtle differences in color, or a color shift when a titration kit is finished.

For this reason alone, I personally prefer the hanna kits(minus the calcium kit as that just has to many instances where errors can be introduced) as they give me a hard number without judging color changes, or comparing colors that never match what they should.

Is there one simple calcium test kit that provides consistent test results. I've had so many different readings with Salifert, Read Sea, and Hanna calcium test kits, not to mention the vague instructions.

If you stick to one test kit, the repeatability of the result is a matter of consistent application of the test process.

Consistency between different brand hobby grade test kits will only happen by chance as they are not particularly accurate.

Never had an issue with salifert. Always repeatable back to back.

If you cannot get reasonable results(within stated error rates), I would question the procedure over the actual test.

I have hanna test kits for almost everything with mag on the way. I use aquaforest for mag right now and will continue for spot checks and use salifert for spot checks as well when something doesnt seem right. Good way to double check the hanna's. Calcium is tricky but have written them for how to get more accurate results there is a good youtube video for hanna calcium where he explains it the same way i was explained by hanna. Since the explanation the kit seems to be more accurate.

I tried many brands and settled on this:
Kh and ca: salifert.
Mg: I use salifert but aqua forest is also good.
Phosphate and nitrate: nyos and hannah, salifert is decent for these two but difficult to match colors exactly.

I use salifert for all but phosphate - then, Hannah Ultra Low. All of these are as reliable as the hobbyist using them.

Most all of them use the same methods, just in different quantities, so work on your skill and make sure that they are not too far out of date.

Have you been happy with the Hanna Mg tester?

There has been good bad and ugly. I have been using my aquaforest test kit for mg more then my mg hanna was waiting for the hype and issues with the reagent to sort itself out before using more frequently.
