Aquascape Cold Water Beneficial Bacteria is specifically formulated to maintain clean, clear, and healthy water in ponds during cold weather. Ideal for temperatures below 50°F (10°C), this concentrated treatment contains eight pure strains of beneficial bacteria that actively reduce ammonia, nitrite, and organic waste—even when water temperatures drop. Safe for all pond life, it also contains marigold and vitamin B to naturally enhance fish color and promote health throughout the colder months.

  • Reduces Harmful Waste: Lowers ammonia, nitrite, and sludge buildup that accumulates during fall and winter.
  • Safe for All Pond Life: Non-toxic to fish, plants, pets, and wildlife.
  • Supports Fish Health: Added marigold and vitamin B promote immune function and vibrant coloration.
  • Concentrated Formula: Eight pure strains of bacteria ensure consistent and powerful results.

PRO-TIP

Apply Cold Water Beneficial Bacteria during fall and early spring to get ahead of organic buildup before temperatures rise. Avoid using other chemical treatments simultaneously, and turn off UV clarifiers for 48 hours to allow bacteria to establish.

Not Recommended For

  • Rapid removal of algae—this product is for long-term biological balance
  • Use as a substitute for mechanical filtration or pond cleanouts
