Powerful Probiotic Blend for Enhanced Water Quality and System Health


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.


Applications :

PRB is available in two concentrations to suit your specific needs:


  1. PRB Standard (Aquarium Strength)

    • Dose Rate :
      • 5ml per 50L of water.

    • Water Treatment per Bottle :
      • 100ml bottle : Treats 1,000L of water.
      • 250ml bottle : Treats 2,500L of water.
      • 500ml bottle : Treats 5,000L of water.
      • 1L bottle : Treats 10,000L of water.

  2. PRB Aquaculture Strength

    • Dose Rate :
      • 1ml per 200L of water (50,000 CFU/ml concentration).

    • Water Treatment per Bottle :
      • 1L bottle : Treats 200,000L of water.

    • Pond Dosing : PRB can be cultured on-site for large-scale applications, using OC-K Nutrient to maximize bacterial growth.

OC-K Nutrient: The Complete Fuel for Microbes and Macrophytes

Microbes are only as good as their core nutrition.


OC-K Nutrient is a carefully formulated, totally organic blend that provides essential nutrients and fuel sources for bacterial growth. It contains a balanced mix of amino acids , nitrogen , proteins , phosphorus , and both macro and micro elements —all of which are necessary for optimal bacterial propagation.


Key Benefits :

  1. Complete Nutrient Profile 🌾
    OC-K supplies a broad spectrum of nutrients, including:

    • BOD (Biochemical Oxygen Demand) to support bacterial metabolism.
    • Direct carbon source to fuel bacterial growth and enhance efficiency.
    • Amino acids and proteins for sustained bacterial activity.

  2. Critical for Pond-Side Culturing ⚗️
    OC-K is essential for culturing beneficial bacteria pond-side , such as NCOMP and PRB, allowing users to multiply bacterial populations on-site. This cost-effective method enables large-scale applications without the need for excessive product use.

  3. Organic & Alcohol-Free 🍃
    Unlike some bacterial fuels, OC-K is entirely organic and does not contain alcohol-based compounds, ensuring it is safe for aquatic life and the surrounding environment.

  4. Food Source for Filter Feeders 🦐
    OC-K doubles as a food source for bacteria, plankton, zooplankton, and other filter-feeding organisms , making it a versatile addition to any aquatic ecosystem.


Recommended Dosing :

  • Aquaculture : 50ml per 1,000L of water.
  • Aquarium : 1ml per 200L of water.

OC-K is effective for supporting bacterial growth in both routine applications and pond-side culturing and for promoting nutrient cycling in planted aquariums.


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

Choose the Right Concentration for Your Needs :

  • PRB Standard (Aquarium Strength) : Perfect for smaller-scale applications like home aquariums or nano systems. Available in 100ml, 250ml, 500ml, and 1L .
  • PRB Aquaculture Strength : Ideal for larger-scale operations, including RAS, hatcheries, biofloc systems, and open ponds. Available in 1L .

Enhance your aquatic system’s health and performance with PRB and OC-K Nutrient —your trusted partners in water quality management.
