Kusuri PRO-100 koi bacteria is a powerful, high-concentration liquid of beneficial bacteria. It’s a non-chemical, preventative treatment that outcompetes harmful pathogenic bacteria (like Aeromonas and Pseudomonas) by starving them of nutrients. Use it regularly to boost fish immunity and promote a stable, healthy pond environment.

What is Kusuri PRO-100 and Why is it Essential?

Kusuri PRO-100 is arguably the most powerful biological aid available to fish keepers. It offers an effective, non-chemical solution to a major pond health risk: pathogenic bacteria. Dangerous strains like Aeromonas and Pseudomonas often cause catastrophic fish losses through wounds and ulcers. Therefore, a reliable preventative treatment is essential for maintaining a resilient koi pond. This proactive approach supports overall fish vitality and reduces stress, which are key factors in resisting disease.

Kusuri PRO-100 Koi Bacteria: Starving Out Harmful Pathogens

This product is neither an antibiotic nor a disinfectant. Instead, it uses a powerful biological mechanism: competitive exclusion.

 The Science Behind Competitive Exclusion

• We use a highly concentrated liquid of beneficial, non-pathogenic bacteria, guaranteed at 100 billion organisms per ml.
• These safe colonies multiply rapidly in your pond water.
• Crucially, they aggressively out-compete the harmful strains for the available food source (organic waste).
• In short, PRO-100 starves out and replaces the dangerous bacteria, reducing their numbers significantly without the use of harsh chemicals.
• The continued use of Kusuri PRO-100 koi bacteria helps maintain this crucial balance, ensuring that dangerous bacteria never reach a harmful concentration level.

Key Benefits and Filter Safety

• Non-Chemical Prevention: No need for harsh chemicals or antibiotics. It’s safe for plants and wildlife.
• Reduces Pathogens: Effectively lowers the count of free-living Aeromonas and Pseudomonas in the water.
• Aids Natural Recovery: By reducing the bacterial load, it naturally supports the fish’s therapeutic recovery from infections.
• Filter and UV Compatibility: Kusuri PRO-100 koi bacteria is completely safe for biological filters and media. While it is recommended to switch off UV and Ozone for 24-48 hours after the initial application to allow the new bacteria to establish, it will not harm filter bacteria. Aeration should be increased during this initial setup period.

Dosage and Application Directions

Note: Always shake well before use. Add the correct dose directly to the pond in an area of good water flow.

Cold Water Dosing (Below 15°C)

Below 15°C double the maintenance dose to 20ml per 4550 litres every five days to compensate for slower bacterial activity.

How Kusuri Sludge Buster Works to Clean Your Pond

Sludge Buster targets the organic waste that accumulates in hard-to-reach areas—including pipework, filters, and folds in the pond liner. Regular use of this highly concentrated liquid prevents the buildup of these organic sediments, which can otherwise cause major water quality problems.

The beneficial bacteria in Kusuri Sludge Buster Koi offer several important advantages:

• Improves Water Clarity: Removes the microscopic particles that contribute to hazy or cloudy water.
• Boosts Oxygen Levels: It significantly reduces the Biological Oxygen Demand (B.O.D.), meaning more oxygen is available for your fish and biological filter.
• Enhances Filter Performance: Keeps pipework and filter media cleaner, improving pump flow rate.
• Ideal for Bottom-Drain-Free Ponds: It is the perfect treatment for ponds without a bottom drain system where waste naturally settles.

When and How to Use Sludge Buster

Kusuri Sludge Buster is most effective when used regularly. It is ideal as both a routine maintenance treatment and a seasonal boost.

Seasonal and Routine Application:

• Spring & Autumn: Use as a deep clean during seasonal changes when biological processes are adjusting.
• Routine Use: Best applied weekly or at least once a month to maintain cleanliness.

Crucially, for best results, the beneficial bacteria are most active when the water temperature is above 15°C. You can easily check your temperature with one of our Pond Thermometers.

The standard dosage is 100 ml per 1000  litres (220  gallons) of pond water. Simply dilute the required amount in a bucket of pond water and distribute it evenly around the pond’s surface.2 This gentle biological cleaner is completely safe for pond fish, plants, and established filters.

Key Benefits of Bao Bio+ Pond Bacteria

Bao Bio+ does more than just enhance filtration. It actively defends your fish and improves overall water quality.

• Pathogen Reduction: The powerful bacterial strains organically reduce harmful Pseudomonas and Aeromonas—known causes of ulcer and hole disease—by up to 99.9 percent within just four weeks.
• Waste Elimination: It effectively targets and reduces organic waste, including toxic ammonia, nitrite, nitrate, and phosphate, which contribute to poor water quality and clarity.
• Filter Support: It colonizes the filter media, dramatically boosting the biological capacity of your pond filter system.
• Fish Health: By creating a healthier environment and reducing internal parasites, the product indirectly supports the Koi’s immune system. This also promotes better nutrient digestion and growth.

The Science Behind Bao Bio+ Filtration

Furthermore, Bao Bio+ uses competitive exclusion, which is unlike treatments that rely on harsh chemicals or antibiotics. The introduced beneficial bacteria consume the food sources and resources that the harmful pathogenic bacteria (like Aeromonas and Pseudomonas) need to thrive. Consequently, the population of pathogens is naturally and organically reduced. This happens without harming your fish or the essential nitrifying bacteria in your filter. This action also greatly minimizes the accumulation of sludge and organic detritus at the bottom of the pond. <a href=”[Internal Link: Pond Filters Category]” target=”_self” title=”Explore Our Pond Filtration Systems”>Browse our range of pond filtration systems here.</a>

Dosage and Application for Bao Bio+ Pond Bacteria

Bao Bio+ is simple to use and completely safe for your fish, plants, and filter system.

• Standard Dose: Apply 2.5 grams per 1,000 litres of pond water every week.
• Method: For best results, dissolve the measured powder in a small amount of pond water first. Dose the resulting solution directly into your biological filter media to ensure the bacteria immediately colonize the necessary surfaces.
• Cold Water Use: If pond temperatures are below 15 degrees Celsius, dissolve the powder in a little warm water first to help activate the culture before adding it to the pond.

Choose the size that is right for your pond. Options are available from 250g up to 2.5kg and larger, ensuring you always have enough of this vital Pond Bacteria on hand.
