CO2 Scrubber for aquarium protein skimmer

thingiverse

A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO2) from the ambient air. Carbon Dioxide (CO2) can directly affect the pH of your aquarium, and with a low pH, corals may not grow as fast. Connecting a CO2 scrubber directly to the venturi on your protein skimmer along with CO2 absorption media you can control the amount of CO2 that is being sucked into your skimmer, effectively raising the pH of your tank by removal of excess CO2. CO2 is one of the most common causes of low pH in household aquariums. Ambient CO2 can vary from building to building and depending on your location it may not be possible to maintain a consistent source of fresh air from the outside into the protein skimmer. By relocating the protein skimmer’s air intake from the silencer over to the CO2 scrubber, it can actually increase your tanks pH by a couple of 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 of days. Results may vary. Size: 110x110x220mm - 1 litre This CO2 Scrubber is designed to hold CO2 Absorbent Media (Soda Lime). Don't forget to place a sponge inside between the bottom grill and the absorbent media.
