Filter for CO2 Removal – CO2 Scrubber.
CO2 is by far the number one cause of low pH in household aquariums. Ambient CO2 can vary from building to building and depending on your location it may not be practical to keep your windows open or pull fresh air from outside into the skimmer.
There is a solution!
By directing your protein skimmers air intake to pass through the CO2 scrubber first, you can actually increase your tanks pH by a couple points. Depending on the amount of ambient CO2 in the room it is not uncommon for tanks to raise from 7.8 pH up to 8.3 pH within a couple days, however results can vary.
