U.P. Aqua Co2 Indicator not working?
OK. So since Darkblade said it was not recommended to mess with the 4dkh solution, I did something g today that can also get the blue color instead of green.
1. Drop only one drop bromothymol blue
2. Add 4dkh solution once per drop and well mix the fluid before continue to next drop.
3. Monitor the color of the fluid after each drop, until you see the color changed from green to blue ( mine turned to blue after I fill the cap about 2/3 full).
4. Dump the extra, only leave half cap of fluid in there.
I just put mine in there and still waiting to see if that will work.
