Favorite Alk Test???

[spawn]

Hi I'm just wondering what peoples favorite brand for Alk tests are?
I use Elos, but I have a hard time seeing the color change most of the time & have to ask my wife to watch for it as I test. Pretty sure I'm color blind & wonder if there is an easier to read one that people like?

Too bad nobody in Canada sells the Tropic Marin Alk test kit. The color change is very definite. Best kit I've ever used.

go with the Hanna digital ALK test kit the result is in numerical value.

I also used Salifert and Elos test kit before purchasing the unit above.

I use the Salifert test kits.

Seams to be really good.

I use ELOS.

I also use half the water for the test and then the number of drops used is the ALK Reading... still very accurate and doubles up your ALK tests for good $$$ savings.

Hanna Alk Checker. Doesn't get easier to read. And pretty darn accurate.

For a quickie, I use (gasp!) the aquarium pharmaceuticals test. It's a simple titration with a dropper bottle. It's accurate to +/- 1 dKh and that's all I need to tell me if my alk is stable.

I like the Hanna tester for low range phosphate measurement. None of those standard test kits give me anything close to the accuracy of this one and are useless in telling me if I'm above critical levels that would cause me problems for my sensitive corals.
