Ive recently looked into the CO2 scrubbers for raising pH in the aquarium. Coralvue makes a reasonable little unit, which comes with CO2 media. However, im a bit confused. All the soda lime Ive seen (in the veterinary field) and available from other aquarium manufacturers turns from white to violet when exhausted. However, the Coralvue media turns from violet to white (per the packaging). When you look it up on their website, at https://www.coralvue.com/icecap-color-changing-co2-absorbent-media-1kg, it says both (pink to white, and white to pink). Did Coralvue engineer a media that has opposite color change (for no real reason), or are they just mistaken, and potentially selling exhausted media?
