Alkalinity tester

[mook1178]

I am thinking of switching to another alkalinity tester. I currently use Salifert an an thinking of switching to Hanna.

I am struggling to keep a stable alkalinity and I feel part of that is due to not going to a consistent color in the salifert kit. I am thinking the Hanna, will be more consistent in that regard.

Is there a better test kit over Hanna? I am getting into Across and still trying to dial in my parameters. The last one I'm struggling with stability is alkalinity.

Hanna is good, got my dosing dialed.

Hanna is good for alkalinity, better than Salifert, however I think both are pretty good if you're consistent.
I would use Hanna exclusively if the reagent was not 18.00 for 25/test.
I also use Aquaforest which I like as well.

What do you mean not a constant colour with salifert, you have to keep adding a drop until it goes pink, it will go through green/purple first.
