Oracle CO2 Checker

Oracle CO2 Checker

Product code: 12001

Cal Aqua Labs’ Oracle combines the elegance of a glass CO2 checker with a white background inside the solution chamber for increased contrast and easy reading.

Observing the solution color in typical CO2 checkers can sometimes be difficult if placed against dark background or in front of plants since the background color often interferes with the solution color.

The Oracle addresses this issue by placing a small white column at the center of the solution chamber. The white background allows accurate color identification regardless of background. For aquariums that do not require the additional contrast, the insert can be carefully removed.
