I can't see why not. Toss some bromothymol blue into DI water and let CO2 reach equalibrium in the trapped air pocket. walah. No real magic there...just a nice piece of glassware for it to happen in. | |

No real magic there | that sounded like magic to me  looks like it's out of stock on adg, would it work if i buy the adg liquid and use it in some other dropchecker made by redsea? | |

And there really is no reason the indicator would need re-filling unless you spill it. | |

From what I understand, it's nothing more than a pH indicator. | |

Salt, yup! ADA looks to use bromothymol blue but I am not sure what RedSea uses. | |

Curious, if this works and is accurate why dont everyone use them? Wouldnt it be very very helpful to have constant co2 monitoring? Even if it's just low, normal, or high indicator? | |

Cause some people already know if their co2 is set at the right levels. Some don't want more equipment in the tank. This is not a necessity in my opinion if yout plants are doing great. | |

I was very interested in using one of these until I realized just how hard it is to measure pH accurately using a test kit with a color chart to match the color to. This complicates that color matching because the color is now in the water in the tank. Then I found that the KH/pH method, which this is, can say I have 30 ppm, when I only have 5 ppm, or it can say I have 120 ppm, when I have less than 30 ppm. So, I gave up the idea. | |
