Elos, API, and some of the newer Salifert test kits have a pinkish orange tritrant, count drops until it changes to blue you get a slight yellow/green in between if you wanna get an idea of the .5 realm of dKH. The salifert is similar, however the test volume size is different as well as the drop size. End result is the same though.
In testing them side by side on different tanks and coming up with the same results, am I an ass in ass-uming that they are the same tritrant?
