Black Water Nano, LLC (dba Black Water Aquaculture), recently announced that they have developed a purely mechanical and cost-effective process to dramatically reduce and eliminate ammonia and nitrite contents in RAS fish and shrimp farming systems. Their nitrite/ammonia removal units have no ongoing operating costs, require no maintenance and are chemical and electricity free.
During the course of pilot studies, the product was effective at reducing ammonia and nitrite levels in both shrimp and fish RAS systems (that were already utilizing bio-floc and bio-filtration systems respectively) to undetectable levels within a week of installation with no indication of ill effects (including gas bubble trauma) on the specimen shrimp and fish.
The improved water quality offered by the ammonia/nitrite mitigation units have allowed fish and shrimp farmers to safely feed at up to a 40% greater rate per day (with similarly accelerated growth timelines).
Tertiary benefits to their system include: (i) a reduction and prevention in the formation of bio-film throughout the tank system, and (ii) a reduction in anaerobic bacteria plate counts. These forces combine to increase a fish or shrimp farmer’s biosecurity and profitability along with reduced down-time for maintenance.
