Bromo Blue?

[drobbyb]

I've seen people talk about bromo blue as a co2 indicator when used with 4dkh water. Is it the same chemical in the API pH test kit?

 

[coldcazzie]

yes

 

[StandbySetting]

Yes, in the standard PH test kit not the high range one.

 

[nurglespuss]

Aye,

also if you know anyone that works in a lab, its readily available as a staining agent (though should NEVER be washed down a sink), you can get a lifetimes supply for £20.
