Electronic GH meter/tester


Is there such a thing and if so who makes one. I am lazy and the drop check method sucks. Unless someone can tell me a really good one that changes color instead of kind of chamges color

I am not aware of an electronic GH meter.

However, I have read reviews that LaMotte makes an excellent (albeit pricey) GH test kit.

I use my tds meter for water change water. Whatever remineralizer you're using will hit a corresponding tds for gh values.

A meter for this actually does exist, it uses ion selective electrodes. You would need to get a divalent one for measuring gh. Probably very expensive, and not worth it for our hobby.
