I thought I would try this DIY project (most powerheads can be modified in a similar fashion) to inject CO2 into an aquarium. This modification provides a flow rate of 60 - 80GPH and the filtration housing/reactor can handle ≤ 4-5bps with no misting and no noise. Perfect for yeast generators, placing the filter on a timer allows the CO2 in the main chamber to gas off at night when the pump is turned off. BUMP.
