Hi
Did anybody run into similar problem?
Indicator solution turns clear after 3-4 days.
It worked fine for first two weeks then I replaces solution and after 4 days it turn clear so I cleaned the checker and replaced solution and again after 4 days is all clear .
Can you tell me what is wrong?
Indicator made by Calaqualab.
Thank you,
BobasEB

If you have a pH test kit, with the color card showing blue as pH 7.6 and yellow being pH 6 or so, you can add a drop of that to the fresh solution in the bulb and it should work fine.

Put it lower or in a shaded area of the tank - it's light sensitive.
