Drop Checker

does this thing work?

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.

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?

99.9% sure that they work on the same principle...just would need the Red Sea CO2 color scale if it is a different indicator. 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.
