Product Information

Full details

NT Labs Koi Care Filter Bugs is a specialized bacterial supplement designed for pond keepers looking to establish or maintain a robust biological filtration system. It is ideal for pond owners performing seasonal spring restarts, setting up new filters, or recovering from water quality imbalances caused by treatments or heavy cleanings. While the product is highly effective at neutralizing harmful ammonia and nitrite, it requires the temporary deactivation of UV sterilizers to ensure the bacteria successfully colonize the pond filter media.

Extended Product Information

FAQs

Can I use this product with tap water conditioner?

Yes, but it is best to add the bacteria a few hours after the conditioner to ensure the chlorine is neutralized.

How long should I leave the UV light off?

You must keep the UV light off for at least 24 hours post-application.

Is this product safe for sensitive fish species?

Yes, it is formulated to promote a healthy biological environment which is safe for all pond fish.

Can I overdose the pond with bacteria?

While the product is safe, it is always recommended to follow the dosing instructions on the bottle for cost-efficiency.

Does it work in cold water?

Nitrifying bacteria work slower in cold water; performance is optimal when water temperatures are rising in the spring.

How do I store the bottle?

Keep it in a cool, dark place and ensure the cap is tightly closed to prevent contamination.

Troubleshooting

Ammonia levels remain high after dosing

Ensure the UV lamp was turned off for the full 24 hours and verify the filter flow rate is adequate for the pond volume.

Cloudy water after adding the product

This is often a natural reaction as the bacteria establish themselves; ensure oxygen levels are high in the pond to support the bacterial bloom.

Pros and Cons

Pros

  • Significantly speeds up the maturation of biological pond filters
  • Helps restore water balance after chemical treatments or filter maintenance
  • Contains multiple essential bacterial strains for a complete nitrogen cycle
  • Highly cost-effective with a large total volume capacity
  • Easy-to-apply liquid formulation

Cons

  • UV clarifiers must be switched off for 24 hours during application
  • Requires careful dosing to match total pond volume
  • Best used within a specific temperature range for maximum bacterial activity

Setup, Compatibility & Care

To ensure success, turn off your UV clarifier for at least 24 hours after dosing to allow the beneficial bacteria to attach to the filter media. The product is compatible with all standard pond filters and materials, including bio-rings, matting, and sponges. Store the bottle in a cool, dark place away from direct sunlight to maintain the potency of the live bacteria. Always calculate your pond volume accurately before dosing to avoid waste or under-dosing, and perform routine water tests for ammonia and nitrite to verify the bacterial colonization progress.
