Reef Pure RO Systems colour changing CO2 absorbent media is designed to specifically remove excess CO2 from your protein skimmer’s air intake. Featuring a colour changing dye, this media will turn from white to violet as the media exhausts so you know when it’s time to replace it.

CO2 is typically the largest and most common limiting factor for pH in aquariums with excess CO2 building up to much higher levels indoors than typically found in natural marine environments. With a CO2 reactor, it is not unusual to see increases in pH ranging from 7.8 to 8.3 after a few days of consistent operation.

Increase the pH of your reef aquarium dramatically by attaching a CO2 scrubber to your aquarium. By removing excess CO2 from the air intake of your protein skimmer you can greatly boost pH levels, leading to increased calcification and growth for your corals.
