Directions:

Connect the included 3/8″ tubing to your protein skimmer’s air intake and the output side of the reactor. It is usually easiest to remove your skimmer’s silencer and directly attach the CO2 Scrubber tubing your pumps venturi.

Unscrew the body from the head of the reactor and remove the refillable cartridge. Add 1 Tbsp of RODI water to the bottom of the reactor body making sure that it does not touch the CO2 media when the cartridge is replaced. Completely fill the refillable cartridge insert with your preferred CO2 absorbing media and place back into the reactor housing.

Monitor your tank’s pH hourly for the first couple days of use. When your pH starts to drop in value (usually 1-2 weeks) you will need to replace the CO2 media. Most CO2 absorbing media will have a color changing indicator to let you visually see when it is depleted.
