Only 2 solutions now?

Used to be 2ml of tank water
1 scoop of purple powder
10 drops of bottle2
then titrate that solution to blue with the third bottle?

I still have 2 "older" test kits in my fish cupboard so curious when they changed this.

I have noticed over the years of using salifert CA test, if you add a drop or 2 more of solution 2, the color change is more dramatic and easier to see, but does not change the endpoint.
