Product Introduction

Maintaining clean, stable water is one of the most important factors in keeping fish, shrimp and aquatic animals healthy. Betta4U PSB Live Bacteria is a premium culture of Photosynthetic Bacteria (PSB) developed to support biological filtration, improve water quality and help establish a healthier aquatic ecosystem.

Unlike chemical water conditioners that work immediately but temporarily, PSB Live Bacteria contains living beneficial microorganisms that naturally multiply inside your aquarium or culture system. As these bacteria establish themselves, they support the biological processes responsible for breaking down organic waste and maintaining a balanced nitrogen cycle.

A healthy bacterial population is essential for converting waste into less harmful compounds, helping to maintain cleaner water and a more stable environment for aquatic life.

Betta4U PSB is suitable for freshwater and saltwater aquariums, ornamental fish breeding, shrimp culture, commercial aquaculture and agricultural applications. It is ideal for hobbyists, breeders, fish farms and anyone looking for a natural biological solution to improve water quality.

Because PSB is a live culture, results develop progressively as beneficial bacteria grow and colonise the system. Regular use, together with good aquarium maintenance, supports long-term biological stability.

Concentrated PSB live bacteria designed for freshwater and saltwater aquariums.  One bottle can treat up to 500 litres of water

Contains live bacteria strains, including Nitrosomonas spp., Nitrosococcus spp., Nitrosospira spp., Nitrosolobus spp., Nitrosovibrio spp., Nitrobacter spp., Nitrococcus spp., Nitrospira spp., and Nitrospina spp.

• 100% organic, no heavy metals, no chemicals
• Shelf life: 12 months
• Ideal for new tank setup or enhancing the filter in an existing tank system
• Available in freshwater or saltwater versions
• When mixed with fish feeds, it helps prevent diseases, protects intestinal health, promotes digestion and absorption, encourages growth, and increases feed conversion rates
• Reduces ammonia and nitrite in the tank, decomposes toxic organic waste, sulfate, and nitrous acid
• Establishes a barrier of beneficial bacteria, enhances immunity, repairs damaged mucous membranes of fish, reduces bacterial infection rates, and lowers mortality
• Improves water quality, increases appetite, inhibits the reproduction of harmful bacteria, and enhances fish disease resistance
• Effectively reduces ammonia nitrogen and nitrite, restoring the environment of beneficial bacteria
• Mixed with fish food, it promotes a healthy fish digestive system (for fish food enhancement, use 1-5% of fish feed)
• Enriches water nutrition with protein, vitamin A, B, D, and carotene
• Increases oxygen dissolution rate, raising oxygen supply in water
• Suitable as food for corals, small fish fry, or inverts (0.5 micron)

Common Customer Pain Points

Many aquarium problems are caused by unstable water conditions rather than the fish themselves. Poor biological filtration can gradually reduce water quality and place unnecessary stress on aquatic animals.

Common issues include:

Cloudy or Murky Water

Water that becomes cloudy often indicates excess organic waste or insufficient beneficial bacteria to process decomposing material.

Elevated Ammonia

Fish waste, uneaten food and decaying organic matter naturally release ammonia into the water. Without sufficient beneficial bacteria, ammonia can accumulate and affect water quality.

Fish Showing Signs of Stress

Fish may become less active, lose appetite, hide more frequently or gasp near the water surface when environmental conditions deteriorate.

Unpleasant Water Odours

A strong smell from the aquarium is commonly associated with excess organic waste and an imbalanced biological ecosystem.

Frequent Water Quality Fluctuations

Some aquariums remain unstable despite regular water changes because beneficial bacterial colonies have not fully developed.

Newly Set Up Aquariums

New aquarium systems require time to establish biological filtration before they become fully stable.

Intensive Fish Farming

Aquaculture systems with higher stocking densities require strong biological filtration to support consistent water quality and healthy livestock.

Why These Problems Occur

Every aquarium is a living biological ecosystem. Fish continuously produce waste, while leftover food, plant debris and other organic materials naturally decompose.

During decomposition, ammonia is produced. In a healthy aquarium, beneficial bacteria convert ammonia into nitrite and then nitrate through the natural nitrogen cycle.

However, beneficial bacteria populations can become insufficient due to:

• New aquarium setups
• Overstocking
• Overfeeding
• Cleaning filter media with untreated tap water
• Heavy medication use
• Poor maintenance
• Sudden environmental changes
• High organic waste loading

When biological filtration cannot keep up with waste production, water quality may decline. Cloudy water, unpleasant odours and unstable aquarium conditions can become more common.

Supporting healthy bacterial populations is therefore one of the most effective long-term approaches to maintaining a stable aquarium ecosystem.

Instructions for use:

For New Tank Setup:

• For every 50 litres of tank water, add 10ml of PSB bacteria for the first 7 days, adjusting the dosage when ammonia levels start to fall.
• Switch off the protein skimmer for 1-2 hours when adding bacteria.
• Administer the bacteria during the day or with lights on to maximise effectiveness.
• For maintenance doses, use once a week.

For Established Tank/Maintenance:

• For every 100 litres of tank water, use 10ml of PSB bacteria weekly, monthly, or after every water change.

How Betta4U PSB Live Bacteria Helps

Betta4U PSB Live Bacteria supplies live photosynthetic bacteria that help strengthen the biological ecosystem within aquariums, aquaculture systems and agricultural applications.

When added regularly, the bacteria gradually multiply and establish beneficial colonies throughout the water and filtration system. These microorganisms assist the natural biological filtration process and help maintain a balanced nitrogen cycle.

Regular use may help:

• Support beneficial bacterial populations.
• Improve biological filtration efficiency.
• Help maintain stable water quality.
• Assist in the natural breakdown of organic waste.
• Help reduce ammonia accumulation as part of a balanced biological system.
• Support clearer water over time.
• Promote a healthier environment for ornamental fish and shrimp.
• Support freshwater and saltwater aquarium maintenance.
• Enhance biological stability in breeding and aquaculture systems.

As a live bacterial culture, PSB requires time to establish within the aquarium. Unlike chemical treatments, it works progressively by building beneficial bacterial populations. Consistent dosing helps maintain these populations for long-term water quality management.
