Drop Checker not working
Hey Guys, I have a nano drop checker from Green leaf, along with their 4dkh solution, and indicator solution.
I add a lil 4dkh solution and then add a few drops of the blue indicator solution but the color never gets very dark blue. Its so light it looks clear. I emptied and tried it again this time adding like 6 drops and still it was very light blue, put it in the tank and it looks clear.
Im adding enough to fill the bulb about 1/2 way
Anybody know what is wrong, or if Im doing something wrong?
