Red sea alkalinity test

Suppose to go from blue to green coloration and if yellow then you put too many drops in. It's weird because I don't get that green color or if I do it's very light then i get yello
 
People report problems with test kits fairly regularly. Maybe a local fish store could run a test for you?
 
Got the hanna but needs a refill. I thought I'd use my red sea multi test kit and my aquaforest ones since i have them but yes the hanna is much better.
