Aquatic Plant Central - View Single Post - Does it work? ADA glass dropcheck co2 indicator

I have ADA's drop checker. Instead of filling the checker with aquarium water as they direct, can I fill it with 4 dKH soln and use their pH indicator soln? Or is there something else in their pH indicator soln besides bromothymol blue that will make that not work?
