Universal CO2 Scrubber

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 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.   Requires CO2 Absorbent Media (not included) CO2 is by far the number one cause to 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. By relocating your protein skimmer's air intake from the silencer over to the CO2 scrubber can actually increase your tank's 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 but results can vary.   Directions: Connect the included 3/8" tubing to y
