Too much CO2 in your culture water interferes with the fish’s ability to take up oxygen, even if oxygen levels in your system are adequate. It will also cause the water to become acidic, especially if alkalinity is limited. Therefore, removal of excess CO2 is absolutely critical – especially in reuse and recirculating aquaculture systems.
You can achieve carbon dioxide removal and aeration of the water at the same time using PR Aqua’s forced-air carbon dioxide stripper.
How It Works
Water enters the vessel from the top and cascades inside the column. A blower sized specifically for the desired flow and CO2 removal forces fresh air across the water droplets which results is carbon dioxide being driven off and oxygen being absorbed until the dissolved gases are close to equilibrium with the air (saturation). The treated water drops into the header and is ready for distribution.
