Can I use API pH indicator in my drop checker?
I just got a drop checker and 4KH solution, and realized that I needed a pH reagent! I was looking it up, and a website said:
"Probably the most common would be Bromothymol blue which happens to be the indicator used in Aquarium Pharmaceuticals standard pH test."
Can I use this? Has anyone else used it? How much should I put in?
