CO2 Scrubbing Skimmer Caps

Recirculating CO2 Scrubbers that sit right on your skimmer.

3D printed skimmer cap that recirculates protein skimmer gasses through soda lime to scrub it of CO2.

The cap is designed to sit on top of your existing skimmer cap. It has an air gap and ports to allow overflowing skimmer liquids to seep out. Once the waste gas is out of the skimmer, it is in the ParlaScrubber; it passes through a grate and enters the soda lime portion. the soda lime can be in a bag or loose. Once through the soda lime, the waste gas, now hopefully free of CO2 is then sucked into the skimmer air intake.

The top cap has two 6.5mm O.D. (RODI) tubes protruding from the rim. These tubes should be attached to the skimmer air input.

This product also functions as an effective block to prevent liquid movement. If filter pad or activated carbon is inserted instead of soda lime it can be used to prevent skimmer waste from entering a canister-style CO2 scrubber setup.
