Probiotic Aquaculture Water Treatment | Fish & Shrimp Farms

Aquaculture is the fastest-growing food production sector in the world — and water quality is its single greatest limiting factor. In intensive fish and shrimp farming, organic waste accumulates rapidly: uneaten feed, faecal matter, and dead algae decompose to produce ammonia, nitrite, and hydrogen sulphide. These compounds suppress fish immune function, reduce feed intake, and create the anaerobic conditions in which pathogenic bacteria — Aeromonas, Vibrio, Pseudomonas — proliferate.

Traditional approaches rely on chemical treatments, UV sterilisation, and ozone. These are effective against acute bacterial challenges but do nothing to address the underlying organic loading that drives the problem. Chemical biocides are incompatible with prawn and shrimp sensitivity, and UV systems are expensive to run and cannot treat settled sludge layers.

Sanitify Probiotic Aquaculture Treatment works at the biological level. A consortium of Bacillus subtilis, Bacillus licheniformis, and Bacillus fermentis is dosed directly into the water column. These organisms degrade organic sludge at the pond or tank bottom, reduce ammonia and BOD, suppress Vibrio and Aeromonas proliferation, and improve dissolved oxygen levels — creating the conditions for optimal fish and shrimp growth without chemical inputs.

Dose the Pond — Restore Biological Balance

Add Sanitify to the pond or tank by broadcasting concentrate across the water surface or distributing through aeration equipment at 5ml per 1,000L. Bacillus bacteria distribute throughout the water column and colonise pond floor sediment within 24–48 hours. Re-dose every 3–4 weeks or as indicated by ammonia and BOD monitoring.

The Sanitify aquaculture formula contains a blend of Bacillus subtilis, Bacillus licheniformis, and Bacillus fermentis — three species with complementary metabolic capabilities proven effective in pond and recirculating aquaculture system (RAS) environments. Each organism produces a different array of hydrolytic enzymes, ensuring complete degradation of the major organic substrate fractions present in aquaculture systems.

Bacillus subtilis is the primary organic matter degrader, producing high-activity protease and amylase. Bacillus licheniformis produces lichenase and lipase, targeting lipid-rich feed residues. Bacillus fermentis contributes the competitive exclusion and bacteriocin activity that suppresses Vibrio and Aeromonas — the two most economically significant pathogens in global shrimp and salmon aquaculture respectively.

All three species are spore-forming, giving the product a shelf life of 24 months and stability across a wide temperature range (5–40°C). Spores germinate and become metabolically active within 2–4 hours of entering the water column, reaching effective population densities within 24 hours of dosing.

Safety profile: all three species are non-pathogenic to fish, shrimp, humans, and wildlife. The product has no ecotoxicity classification and is compatible with effluent discharge standards across EU member states.
