PRB is a carefully formulated probiotic blend designed to promote bioremediation , enhance nutrient cycling , and mitigate pathogens in both aquaculture and aquarium systems. Whether you’re managing a large aquaculture operation or a home aquarium, PRB supports water quality, solid waste digestion, and overall system health.

Key Benefits :

1. Enhanced Nutrient Cycling 🔄
   PRB bacteria play a critical role in balancing the nutrient cycle by assimilating solid and dissolved waste . They digest a wide range of organic matter, including:

   • Fats, lipids, starches, proteins, cellulose
   • Excess food, excrement, dead plant material, and vegetation
   
   

2. Biological Pathogen Mitigation 🛡️
   PRB helps control harmful pathogens through:

   • Competitive exclusion : Outcompeting harmful bacteria for space and resources.
   • Production of antagonistic compounds : Naturally occurring compounds produced by PRB bacteria inhibit the growth of harmful pathogens such as:
     • Columnaris
     • Streptococcus
     • Aeromonas
     • Vibrio (particularly effective for Vibrio control).
   
   

3. Aquaponics Compatibility 🌱
   PRB is highly compatible with aquaponic systems , where it colonizes plant roots, enhances nutrient uptake, and stimulates the immune response of aquatic organisms.

4. Extensive Enzyme Production 🧪
   PRB bacteria produce a variety of enzymes that aid in the breakdown of complex organic compounds, improving water clarity and reducing sludge buildup.

5. Supports Gut Health 🐠
   When ingested, PRB bacteria contribute to the gut health of aquatic organisms, improving feed conversion rates and overall resilience.

6. Biofloc System Enhancement 🌊
   PRB is particularly useful in biofloc systems , where it helps regulate and boost biofloc formation, maintaining stable water quality and nutrient levels.

1ml per 100L - Once per week

2. 
   
   Water Treatment per Bottle :
   • 100ml bottle : Treats 10,000L of water.
   • 250ml bottle : Treats 25,000L of water.
   • 500ml bottle : Treats 50,000L of water.
   • 1L bottle : Treats 100,000L of water.

PRB is STRONG, we recommended starting off at 25% of the recommended dose and adjusting accordingly for water quality and stocking density/nutrient levels. 

Frequency of dosing can vary from once per week to once per month depending on application

Pond-Side Culturing Instructions :

For large ponds, PRB can be cultured on-site for more cost-effective dosing using OC-K Nutrient :

1. Use source water from the pond and sterilize or dechlorinate it.
2. Fill a container with the sterilized water.
3. Add 1ml of PRB per litre of culture volume .
4. Add 5ml of OC-K nutrient per litre of culture volume .
5. Aerate the mixture for 24-48 hours , depending on temperature (24 hours at 25°C).
6. Dose the cultured product into the pond at 1000ml per 1,000,000L of pond water.

Dose Rate & Frequency :

These are recommended starting doses . The actual dose rate and frequency should be adjusted based on:

• Stocking density
• Waste accumulation levels
• Specific water quality issues
