Natural Supplement for Fish Fry — Photosynthetic Bacteria (PSB), 36 oz
Photosynthetic bacteria (PSB) are live, beneficial microbes that support fry growth, resilience, and water quality. This 36 oz bottle provides an eco-friendly, low-effort way to enrich fry diets while helping keep rearing tubs balanced.
- Nutrient-rich: Natural proteins, amino acids, and vitamins to support early development.
- Digestive support: Encourages a healthy gut microbiome for efficient nutrient uptake.
- Immune support: Bioactive compounds help bolster fry resilience.
- Cleaner water: Assists in breaking down dissolved organics, discouraging harmful spikes.
- Higher survival potential: Consistent use promotes sturdy, fast-starting fry.
Packaged in a recycled PET container to minimize leaks and preserve freshness during transit. For best results, store in warm, full sunlight to keep the culture active.
Ideal for breeders maintaining multiple fry tubs who want a live, scalable supplement.
How to Use
Dosage: Start with 2–5 mL per gallon (0.5–1.3 mL/L), daily or every few days depending on stocking and water quality. Increase gradually if water remains clear and parameters are stable.
With other foods: Safe to use alongside powdered fry foods, infusoria, and baby brine shrimp.
Method: Shake gently, add near flow/aeration, and observe. Maintain good aeration and regular small water changes.
Storage: Keep the bottle upright in a warm, sunny location. Avoid freezing. If light-deprived, culture may slow—restore sunlight to reactivate.
Notes & Disclaimer
Odor is normal: Live PSB can produce a strong, sulfur-like smell (e.g., trace H₂S)—this is expected and harmless in typical use.
Monitor ammonia, nitrite, and pH regularly, especially in dense fry setups. Reduce dosage if water clouds persistently.
For aquarium use only. Not for human or animal consumption. Keep out of reach of children and pets.
